The equation of simple harmonic progressive wave from a source is y =15 sin 100πt. Find the equation of the wave generated if it propagates along the + X-axis with a velocity of 300 m/s.
Solution:
Given: Equation of source y =15 sin 100πt, Direction = + X-axis, Velocity of wave v = 300 m/s.
To Find: Equation of the wave =?
Equation of Source wave is y =15 sin 100πt
Comparing with y =15 sin 2πnt
a = 15 m and 2πn = 100 π
∴ n = 50 Hz
