Intensity

Assertion (A) : The maximum intensity in interference pattern is four times the intensity in interference pattern is four times the intensity due to each slit of equal width. Reason (R ) : Intensity is directly proportinal to square of amplitude.

The intensity of the light coming from one of the slits in a Young's double slit experiment is double the intensity from the other slit. Find the ratio of the maximum intensity to the minimum intensity in the interference fringe pattern observed.

Two coherent sources of equal intensity produce maximum intensity of 100 units at a point. If the intensity of one of the sources is reduced by 36% reducing its width, then the intensity of light at the same point will be

In Young’s double slit experiment, the intensity of light coming from the first slit is double the intensity from the second slit. The ratio of the maximum intensity to the minimum intensity on the interference fringe pattern observed is

The intensity of illumination on a surface from a source of light varies-inversely as the square of the distance of the surface from the source. The effect of moving a piece of paper 3 xx as far from the source is to multiply the intensity by 3 divide the intensity by 3 multiply the intensity by 9 divide the intensity by 9

Assertion Two coherent sources transmit waves of equal intensity I_(0) Resultant intensity at a point where path difference is lambda/3 is also I_(0) . Reason In interference resultant intensity at any point is the average intensity of two individual intensities.
