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.

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 % 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.

A narrow monochromatic beam of light of intensity 1 is incident on a glass plate as shown in figure Another identical glass plate is kept close to the first one and parallel to it. Each glass plate reflects 25% of the light incident on it and transmits intensities in the interference pattern formed by two beams obtained after one reflection at each plate.

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

Two thin glass plates are placed parallel to each other such that distance between them is very small. Each glass plate reflects 25% of incident energy and transmits remaining 75% Light beam is incident on this system. Consider the interference of two light beams obtained after one reflection from each glass plate. Calculate ratio of the maximum to minimum intensity.

A plate is kept in front of a beam of photons. The plate reflects 40% of the incident photons and absorbs the remainder. If the plate absorbs energy at a rate 1200J^(-1)s , find the net force acting on it.

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 beam of light strikes a glass plate at an angle of incident 60^(@) and reflected light is completely polarised than the refractive index of the plate is-

A ray light of intensity I is incident on a parallel glass-slab at a point A as shown in figure it undergoes partial reflection and refraction. At each reflection 20% of incident energy is refracted rays AB and A'B' undergo interference find the ratio I_(max)//I_(min)
