Question

A wave has a wavelength of 3m.The distance between the crest and adjacent trough is

Answer 1

The wavelength is the distance between two similar, adjacent phases of the wave; like from trough to trough or Crest to Crest. Now we can write the distance

Crest2crest = crest2trough + trough2crest

And assuming symmetry

Trough2crest = crest2trough

We have wavelength =

Crest2crest = 2* crest2trough = 2 *20cm

= 40cm

Answer 2

ANSWER:-

Crest2crest = crest2trough + trough2crest

And assuming symmetry

Trough2crest = crest2trough

We have wavelength =

Crest2crest = 2* crest2trough = 2 *20cm

= 40cm
