The ratio of amplitude of two waves is 2:3. What is the ratio of intensities of these waves?

The ratio of volumes of two cones is 4:5 and the ratio of the radii of their bases is 2:3. find the ratio of their vertical heights.

Ratio of intensity of two waves is given by 4:1. Then, ratio of the amplitude of the two waves is:

The widths of two slits in an interference experiment ar in the ratio 9:1.What is the ratio of amplitudes and intensitites of light waves from them?

Two light waves of amplitudes a_1 and a_2 interfere with each other. write the ratio of the intensities of a maxima to that of a minima.

In the wave picture of light, intensity of light is determined by square of the amplitude of wave. What determines the intensity of light in the photon picture of light.

Transverse waves of the same frequencies are generated in two steel wires A and B .The diameter of A is twice that of B and the tension in A is half that in B.the ratio f the velocities of waves in A and B is:

In Young's interfernece experiment,the ratio of intensity at the maxima and minima in the iterference pattern is 25:9.What will be the ratio of widths of the two slits?

If the ratio of width of two slit's in Young's experiment is 1:25 , deduce the ratio of intensity at maxima and minima in the interference pattern.

If the ratio of width of two slit's in Young's experiment is 1:25 , deduce the ratio of intensity at maxima and minima in the interference pattern.
