When a plane mirror is rotated through a certain angle,the reflected ray turns through twice as much and the size of the image

Where should the light source (bulb) be placed in the reflector of a searchlight or torch so that the light rays travel over a long distance?

$A$ ray of light $XY$ is incident on a spherical mirror as shown in the diagram. Redraw the diagram and mark the normal,angle of incidence and angle of reflection.

Which type of image cannot be obtained by a concave mirror?

If an object is placed symmetrically between two plane mirrors, inclined at an angle of $72^{\circ},$ then the total number of images formed is

If an object is placed between two plane mirrors inclined at an angle of $45^{\circ}$,then the number of images formed will be $9$. State whether this statement is True or False.
