In interference pattern if the slit widths are in the ratio `1:9` then find out the ratio of minimum and maximum intensity

Write ratio of maximum and minimum mass in universe.

A narrow monochromatic beam of light of intensity I is incident on a galss plate as shown in figure. Another identical glass plate is kept close to the first one & parallel to it. Each glass plate reflects 25% of the light incident on it and transmits the remaining find the ratio of the minimum & the maximum intensities in the interference pattern formed by the two beams obtained after one reflection at each plate.

The surface area of two sphere are in the ratio 16:9. Find the ratio of their volumes.

The intensity variation in the interference pattern obtained with the help of two coherent source is 5% of the average intensity find out the ratio of intensties of two sources.

Write ratio of maximum and minimum length in the universe.

A point sources S emitting light of wavelength 600nm is placed at a very small height h above the flat reflecting surface AB (see figure).The intensity of the reflected light is 36% of the intensity.interference firnges are observed on a screen placed parallel to the reflecting surface a very large distance D from it. (A)What is the shape of the interference fringes on the screen? (B)Calculate the ratio of the minimum to the maximum to the maximum intensities in the interference fringes fromed near the point P (shown in the figure) (c) if the intenstities at point P corresponds to a maximum,calculate the minimum distance through which the reflecting surface AB should be shifted so that the intensity at P again becomes maximum.

Two beams of light of intensity I_(1), and I_(2) interfere to give an interference pattern. If the ratio of maximum intensity to that of minimum intensity is (16)/(4) then I_(1):I_(2)= .......
