Question

If the period of a wave is 0.05 s, then what is its frequency?

0.05 Hz

2.0 Hz

10 Hz

20 Hz

Answer 1

Frequency , f = 1/ period , T
1 / 0.05
F = 20Hz ! hope you understand it next time you attempt those type of questions

Answer 2

thanks so much :D

Answer 3

don't forget : v =f lambda
sometimes you might use that also ... they give you period suppose 0.05 s and lambda= 50 mm and find v .. that is speed
so : v = lambda divide by time period T
= ( dont forget to put lambda in metres
