Question

The equation of a wave is given by y=5sin(20x-30t) find the amplitude,velocity, propagation constant, angular velocity, frequency and time period of a wave

Answer 1

Answer:

The wave function is given by y(x,t)=Asin(kx−ωt+φ) y ( x , t ) = A sin ( k x − ω t + φ ) where k=2π/λ k = 2 π / λ is defined as the wave number, ω=2π/T ω = 2 π / T is the angular frequency, and φ is the phase shift.
