define wavelength?

Answer 1

The length between two CONSECUTIVE points on a wave which are directly in phase (or 'in step') with eash other..
Or
The distance between two consecutive crest or trough or any position and a similar position of a particle in the next wave in phase with it is called a wave length.
Or
The length between two CONSECUTIVE points on a wave which are directly in phase with each other. .
Or
the distance between one crest to another crest.
Or
the wavelength is the distance between the midpoints of the wave

It is commonly designated by the Greek letter lambda (λ).

Answer 2

Define Wavelength

Answer 3

The wavelength is the distance between repeating units of a wave pattern.

Answer 4

Wavelength is the distance between two peaks (or two valleys) of the waves of some type of energy that produces regular waves, like light, sound, X-rays, nuclear energy, etc. It's different from frequency, which is the number of complete waves that pass a given point in one second.

Answer 5

Wavelength, distance between corresponding points on two consecutive waves. For example, the wavelength of ocean waves is the distance between one crest and the next, or one trough and the next. Wavelength is a fundamental concept when considering any kind of wave motion, and can vary from very long—for example, hundreds of metres for long radio waves—to very short—for example, million-millionths (10-12) of a metre for gamma rays.

Waves in water and waves on a shaken rope consist of transverse movements of matter, at right angles to the direction of movement of the wave. Crests and troughs are those places where the transverse movement is a maximum.

A sound wave, by contrast, consists of longitudinal movements of air molecules—that is, backwards and forwards movements in the direction of the wave's movement, or opposite to it. Crests and troughs of the wave can be regarded as places where the molecules have moved most from their average positions. Alternatively, crests can be regarded as places where the air molecules are moving fastest in the forward direction, and troughs as places where they are moving fastest in the backward direction.

However crests and troughs are defined, the definition of wavelength is the same: the distance from crest to crest, from trough to trough, or between any two corresponding points.

Answer 6

the min length by which the wave repeats itself is called the wavelength

Answer 7

defined by the symbol lambda (λ) it is the distance between the crests of a wave...it is also the distance between the troughs because of the repeating nature of the wave...
