After reflection, the parallel beam of light appears to come from a point then the type of mirror is ______

When parallel rays are incident on a convex mirror, after reflection they appear to come from……..which is on other side of the mirror ?

After reflection, the light rays from a point object at the focus of a concave mirror,

Explain how a parallel beam of light on reflection from a concave mirror gets converged.

Explain how a parallel beam of light on reflection from a convex mirror gets diverged.

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 ?

A narrow beam of light after reflection by a plane mirror falls on a scale at a distance 100 cm from the mirror. When the mirror is rotated a little, the light spot moves through 2 cm. The angle through which the mirror is rotated is
