Light source of wavelength 400 nm used in a Lloyd's mirror, lies 1 mm above the plane mirror. Find the distance of first minima above the mirror. Distance of the screen from the plane of the sources is 2 m.

In a plane mirror, the perpendicular distance of the image from the mirror is equal to………… .

You are standing at a distance 2 metre from a plane mirror. What is the distance of your image from the mirror ?

A monochromatic light source S of wavelength 440 nm is placed slightly above a plane mirror M as shown . Image of S in M can be used as a virtual source to produce interference fringes on the screen. The distance of source S from O is 20.0 cm, and the distance of screen from O is 100.0 cm (figure is not to scale). If the angle theta = 0.50 xx10^(-3) radians, the width of the interference fringes observed on the screen is –
