Wavelength

Wavelength refer to the distance between successive crests or troughs in a wave. This fundamental property determine many characteristics of electromagnetic radiation, include color in visible light. Measure in meters or specialized units like nanometers or angstroms, wavelength relate reciprocally to frequency through the wave equation.

Radio waves have the longest wavelengths in the electromagnetic spectrum, while gamma rays have the shortest. The wavelength of visible light range roughly from 380 to 750 nanometers, with violet have the shortest wavelength and red the longest within this range.

White dwarf

A white dwarf represents the final evolutionary stage for stars similar to our sun. These stellar remnants form when stars exhaust their nuclear fuel but lack sufficient mass to become neutron stars. Despite being rough earth sized, white dwarfs contain masses comparable to the sun, make them implausibly dense.

White dwarfs nobelium foresight generate energy through nuclear fusion. Alternatively, they gradually cool over billions of years, finally become black dwarfs. The electron degeneracy pressure prepreventsrther gravitational collapse, maintain their structure against their own gravity.

Weight

Weight measure the force exert on an object due to gravity. Unlike mass (which remain constant ) weight vary depend on gravitational field strength. On earth, weight equal mass multiply by the acceleration due to gravity ( (ughly 9.8 m / s² ).)

Scientists distinguish between weight and mass in precise work. An object’s weight changes when move to environments with different gravitational fields (such as the moon ) while its mass remain constant. The siisnit for weight is the newton ( ().)

Chemistry w terms

Water

Water (hHBO)stand as the wewell-nighbundant compound on earth’s surface and a prerequisite for life as we know it. This simple molecule consist of two hydrogen atoms covalently bond to one oxygen atom, form a bent structure with a bond angle of around 104.5 degrees.

Water’s unique properties include high specific heat capacity, surface tension, and ability to dissolve many substances. These characteristics arise from hydrogen bonding between molecules. Water exist in all three physical states at earth’s surface temperatures: solid (ice ) liquid, and gas ( (ter vapor ).)

Weak acid

Weak acids partly dissociate in aqueous solutions, release fewer hydrogen ions than strong acids. Examples include acetic acid (find in vinegar ) carbonic acid, and phosphoric acid. The incomplete dissociation create an equilibrium between the acid and its ions.

The strength of weak acids is quantified by their acid dissociation constan((ke) ), typically express asPKAa log ke)). Higher PKA values indicate weaker acids. Weak acids form important buffer systems that resist pH changes when small amounts of acids or bases are added.

Work function

Work function describe the minimum energy need to remove an electron from a solid material’s surface to a point precisely outside the solid. This property prove crucial in understand photoelectric effects and electron emission phenomena.

Different materials exhibit vary work functions, typically measure in electron volts (eEV) Metals mostly have lower work functions than nonon-metalsmake them better electron emitters. This property influences applications in electron microscopy, photocells, and thermionic devices.

Biology and medicine w terms

White blood cells

White blood cells (leukocytes )form the cellular components of the immune system. Unlike red blood cells, they contain nuclei and appear translucent kinda than red. These specialized cells protect the body against infections and foreign substances.

Several types of white blood cells exist, each with specific functions:

• Neutrophils: first responders to bacterial infections
• Lymphocytes: include b cells and t cells responsible for adaptive immunity
• Monocytes: develop into macrophages that engulf pathogens
• Eosinophils: combat parasitic infections and participate in allergic responses
• Basophils: release histamine during inflammatory reactions

Abnormal white blood cell counts frequently indicate infection, inflammation, or blood disorders.

Wild type

Wild type refer to the phenotype or genotype typically find in nature, serve as a reference point for genetic variations. This standard form represents the almost common variant of a gene or organism in a natural population.

Geneticists compare mutant strains to wild type organisms to understand gene function and inheritance patterns. In laboratory settings, wild type strains provide experimental controls. The concept apply across species from bacteria to plants and animals.

Western blot

Western blotting (iimmunoblot) )entify specific proteins in a sample use gel electrophoresis and antibody detection. The technique separate proteins by molecular weight, transfer them to a membrane, and use label antibodies to visualize target proteins.

The process involve:

1. Protein extraction from samples
2. Separation by gel electrophoresis
3. Transfer to a membrane (blot )
4. Block non-specific bind sites
5. Incubation with primary antibodies specific to target proteins
6. Addition of label secondary antibodies
7. Detection through imaging

This technique prove invaluable in disease diagnosis, research, and protein characterization.

Earth and environmental sciences w terms

Weather

Weathering encompass processes that break down rocks and minerals at earth’s surface without significant transport. Unlike erosion, weathering occur in place through physical, chemical, or biological mechanisms.

Physical weathering fragment rocks without change their composition, oftentimes through freeze thaw cycles, thermal expansion, or root wedging. Chemical weather alters mineral compositions through reactions with water, oxygen, or acids. Biological weathering results from organism activities like lichen growth or burrowing animals.

These processes create soil, release nutrients, and shape landscapes over time. Weathering rates depend on climate, rock type, and exposure factors.

Watershed

A watershed (catchment or drainage basin )define an area where all precipitation drain to a common outlet. These natural boundaries follow topographic features like ridgelines that separate adjacent drainage systems.

Watersheds function as integrate systems where land use affect water quality and quantity. They range from small local streams to massive river systems like the Mississippi basin. Watershed management approach address water resources holistically, recognize connections between upstream activities and downstream impacts.

Wind

Wind represent air movement cause by pressure differences in the atmosphere. Global wind patterns arise from uneven solar heating, earth’s rotation, and geographic features. These air movements transport heat, moisture, and particulates around the planet.

Wormhole

Wormholes represent theoretical structures connect separate points in spacetime. These hypothetical tunnels could potentially create shortcuts through space, allow travel between distant regions fasting than light would ordinarily permit.

While mathematically consistent with Einstein’s general relativity, no observational evidence confirms wormholes’ existence. Theoretical challenges include stability issues and the need for exotic matter with negative energy density. Despite remain theoretical, wormhole feature conspicuously in scientific speculation about advanced space travel.

Wolbachia

Wolbachia bacteria infect numerous arthropod species and some nematodes. These intracellular symbionts transmit principally through female hosts’ eggs, manipulate reproduction to increase their prevalence.

Wolbachia can induce several reproductive alterations:

• Cytoplasmic incompatibility: prevent successful reproduction between infected males and uninfected females
• Parthenogenesis: enable females to reproduce without males
• Feminization: convert genetic males into functional females
• Male killing: eliminate male offspring

Researchers explore wolbachia as biological control agents against disease vectors like mosquitoes carry dengue and Zika viruses.

Whole genome sequencing

Whole genome sequencing determine an organism’s complete DNA sequence. This comprehensive approach reveals the order of all nucleotides in an organism’s genome, provide a foundation for understand genetic variation and function.
