Show that the intensity of a wave is proportional to the square of the amplitude.

A : For best contrast between maxima and minima in the interference pattern of Young.s double slit experiment, the intensity of light emerging out of the two slits should be equa. R : The intensity of interference pattern is proportional to square of amplitude.

The intensity of a wave is (a) Proportional to square of the frequency (b) Proportional to the velocity of wave (c) Proportional to the density of the medium (d) Proportional to the square of the distance of the source from the observer

In simplest terms, the energy of a wave is directly proportional to the square of Its

What is meant by the intensity of a wave ?

A: In the wave picture of light, intensity of light is determined by the square of the amplitude of the wave. R: In the photon picture of light, for a given frequency, intensity of light is determined by the numberof photons per unit area.

Statement-1 : Two longitudinal waves given by equation y_(1)(x,t)=2asin(omegat-kx) and y_(2)(x,t)=a sin (2 omegat-2kx) will have equal intensity. Statement-2 : Intensity of waves of given frequency in same medium is proportional to square of amplitude only.
