A transverse wave has an amplitude of 5 cm, a frequency of 60 Hz and a distance from crest to next trough of 15 cm. Identify the wavelength of this wave.

Question

Please someone help asap I cant figure this out. Is there a formula?

Answer 1

Wavelength is the distance from crest to next crest or from trough to next trough.

15 cm from crest to next trough represents half a wavelength, so take 15 cm * 2.

Answer 2

I still do not understand do you divide or multiply by 2 to get the wavelength?

Answer 3

15 divide 2
wavelength = 7.5cm
