What is the frequency of this oscillation?
What is the phase constant?
a) from graph you can obeserve that 1 wave is taking 4 seconds
to complete a oscillation
therefore frequency is = 1/4 = 0.25 Hz
angular frequency = 2pi/T = 1.57
b) equation of wave is y=Asin(?t+?0) ?0 is phase of oscillation,
A-amplitude=20
at t=0 , y=10 substituting we get 10 = 20 sin(?0) =>sin(?0) =
1/2 => ?0 = 30 degrees
therefore phase constant is ?0 = 30
