Question

what is the wavelength of the wave shown in the figure and how?

Answer 1

★ HEY MATE ★
Here's your answer


WAVELENGTH :-

The distance between two consecutive compression rarefaction is called the wavelength . The wavelength is usually represented by (Greek letter lambda) .

The SI unit of wavelength is metre (m).

Answer 2

Answer: The wave length is 0.16 m.

Explanation:

Given that,

Total distance D = 40 cm

We know that,

The wave length is the distance between consecutive crest to crest of the wave.

According to figure,

The distance between crest to crest = $1\lambda$

The distance between first crest to third crest = $2.5\lambda$

The wave length is

$\lambad= \dfrac{40}{2.5}$

$\lambda = 16\ cm= 0.16\ m$

Hence, The wave length is 0.16 m.
