Question

ways of describing the wavelength of a wave

Answer 1

" Wavelength "

The distance between two successive regions of high pressure or the distance between two successive regions of low pressure.

This is denoted by lambda.

SI unit of wavelength is metre.

Answer 2

✨hey mate! here's your answer!✨

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.

And S.I. unit of wavelength is metre.

hope it is helpful!✌️
