Question

The distance between a crest and a immediate trough in a transverse wave is 20m. find the wavelength​

Answer 1

Explanation:

Distance between crest and trough = wavelength/2

therefore ,

lamda/2=20

lamda=40 m

Answer 2

Answer:

40

Explanation:

To find the we have to use the formula

wavelenth/2

lambda/2=20

lambda =40
