a short note on wavelength
Answers
Answer:
A wavelength is a measure of distance between two identical peaks or crests -- high points -- or between two identical troughs -- low points -- in a wave. Wavelengths represent a repeating pattern of traveling energy, such as light or sound.
Definition: Wavelength can be defined as the distance between two successive crests or troughs of a wave. It is measured in the direction of the wave.
Description: Wavelength is the distance from one crest to another, or from one trough to another, of a wave (which may be an electromagnetic wave, a sound wave, or any other wave). Crest is the highest point of the wave whereas the trough is the lowest. Since wavelength is distance/length, it is measured in units of lengths such as metres, centimetres, milimetres, nanometres, etc.
