A parallel beam of light of intensity I is incident on a glass plate. `25%` of light is reflected in any reflection by upper surface and `50%` of light is reflected by any reflection from lower surface. Rest is refracted The ratio of maximum to minimum intensity in interference region of reflected rays is

A parallel beam of light of intensity I_@ is incident on a coated glass plate. If 25% of the incident light is reflected from the upper surface and 50% of light is reflected from the lower surface of the glass plate, the ratio of maximum to minimum intensity in the interference region of the reflected light is

The reflection from any smooth surface is ______ reflection of light.

A narrow monochromatic beam of light of intensity I is incident on a glass plate. Another identical glass plate is kept close to the first one and parallel to it. Each plate reflects 25% of the incident light and transmits the remaining. Calculate the ratio of minimum and maximum intensity in the interference pattern fromed by two beams obtained after reflection from each plate.

Reflection Of light and Refraction at plane surface

A ray of light of intensity I is incident on a parallel glass slab at a point A as show. It undergoes partial reflection and refraction. At each reflaction 25% of incident energy is reflected. The rays AB and A'B' undergo interference. The ratio I_(max)//I_(min) is

A ray of light is incident from air on a glass plate. It is partly reflected and partly refracted. The phase difference between the reflected and refracted wave is :

Light of intensity 50W//m^(2) is incident on a arae of 1m^(2) in such a way that 25% of light is reflected back. Find the force exerted by light on surface if light incident perpendicularly
