Show that maximum intensity in interfernce is four times the intensity due to each slit. Hence show that interfernce involves only redistribution of energy.

Show that intensity of gravitational field is equal to acceleration due to gravity in the field of earth.

Two coherent sources of light whose intensity ratio is 64:1 produce interference fringe. Calculate the ratio of of intensity of maximum and minmum in the interfernce fring system.

Show that the energy density of em radiation is epsilon_0E^2 . Hence, find the intensity of radiations?

In a Young's double slit experiment,the separation betwen the two slits is d and the wavelength of the light is lambda .The intensity of light falling on the slit 1 is four times the intesntiy of light falling on slit 2.Choose the correct choice(s).

Show that if at some part of a field the lines of force have the form of arcs of concentric circles whose centres are at point O (Fig.), the field intensity at each point in this part of the field should be inversely proportional to the distance from the point to O.

What will be the intensities of the maxima and minima,when the ligth waves interfering with each other are of the same amplitude?Show that the intensity of the maxima is four times the intensity of light due to each of two slits.

In Young's double-slit experiment deduce the condition for constructive and destructive interference at a point on the screen. Draw the graph showing variation of the resultant intensity in the interference pattern against position 'X' on the screen.

In a double slit interfrence experiment the two coherent beams have slightly different intensitties I and I+deltaI(deltaI is lower than I) .Show that the resultant intensity at the maxima in nerly 4 I,while that at minima is nearly zero.

If the two slits in Young's double slit experiment have width ratio 16:1 , deduce the ratio of intensity at maxima and minima in the interfernce pattern.

What should be the width of each slit to obtain 10 maxima of the double slit interfernce pattern ,within the central maximum of teh singel slit diffraction pattern?
