A ray of light after reflection from a mirror is known as

When mirror is rotated through an angle theta , a reflected ray from it moves through an angle of

A beam of light from a source L is incident normally on a plane mirror fixed at a certain distance x from the source. The beam is reflected back as a spot on a scale placed just above the source L. When the mirror is rotated through a small angle theta the spot of the light is found to move through a distance y on the scale. The angle theta is given by

A ray of light falls normally on a plane mirror. What is the angle of incidence ?

In a Lloyds's mirror experiment as narrow slit S transmitting a light of wavelength lambda is placed 3 mm above a small plane mirror ( as shown). The light coming directly from the the slit and that coming after the reflection interfere on a screen placed at a distance of 90 cm from the slit. Length of mirror is 2 mm and the middle point of mirror is 2 mm from point P. If the mirror is shifted towards left then how does the fringe pattern on screen changes ?
