The equation of wave is y=1.0 cos 2pi(...

The equation of wave is
`y=1.0 cos 2pi(t/0.02-x/10)` where t is in second. The frequency of the wave is

A

50 Hz

B

315 Hz

C

10 Hz

D

63 Hz

Text Solution

Verified by Experts

The correct Answer is:
A
Comparing `y=1.0cos2pi (t/0.02-x/10)` with standard equation ,`y=Acos2pi(t/T-x/lambda)` then, `implies T =0.02s`
`Frequency =1/T=1/0.02=50Hz`
