Question 1

A transverse wave of amplitude 0.50 m, wavelength 1 m and frequency 2 Hz is propagating in a string in the negative x-direction. The expression form of the wave is

Question 2

A simple harmonic wave having an amplitude A and time-period T is represented by the equation, y = 5 sin π(t + 4) meter. Then the values of A (in meter) and T (in second) are-
