The equation of the progressive wave is `y = 3 sin[pi(t/3-x/5)+pi/4]` , where x and y are in metre and time in second. Which of the following is correct.A. Velocity `v = 1.5` m/sB. Amplitude `A = 3` cmC. Frequency `f = 0.2 Hz`D. Wavelength `lambda = 10 `m |

Answer» Correct Answer - D Compare the given equation with the standard equation of wave motion, `Y = A sin[2pi(t/T - x/lambda) + pi/4]` where , A and `lambda` are amplitude and wavelength respectively. Amplitude , `A = 3m` Wavelegth, `lambda = 10m`. |
