Two waves are represented in usual notation as y1 = a1 sin (ωt) and y2 = a2 sin(ωt). Their intensities are I1 and I2. What would be the ratio of their amplitude?
Define intensity of a sound. Show that the intensity of a sound for a given frequency is directly proportional to the square of amplitude of the vibration.
If the pressure amplitude of a sound wave is halved, by what factor does the intensity of the wave change?
