`M_(1)` and `M_(2)` are two plane mirrors which are kept parallel to each other as shown. There is a point `'O'` on perpendicular screen just infront of `'S'`. What should be the wavelength of light coming from monchromatic source `'S'`. So that a maxima is formed at `'O'` due to interference of reflected light from both the mirrors. [Consider only `1st` reflection]. `[D gt gt d, d gt gt lambda]`

M_(1) and M_(2) are plane mirrors and kept parallel to each other. At point O, there will be a maxima for wavelength lambda . Light from a monochromatic sources S of wavelength lambda is not reaching directly on the screen. Then, lambda is

Two mirror M_(1) and M_(2) make an angle phi with line AB . A point source S is kept at a distance r from the point of intersection of mirror. A small hemispherical annular mask is kept close to S so that no ray emanting from S directly reaches the screen kept at a distance b from the source. Interference pattern of rays reflected from M_(1) and M_(2) is oberved on the screen. Find the fringe width of this interference pattern lambda= wavelength of light being emitted by source.
