What is silvering of a mirror ?

Give types of mirror.

Diameter of spherical mirror is 10 cm, what will be aperture of mirror ?

Suppose that the lower half of the concave mirror.s reflecting surface as shown in figure is covered with an opaque (non-reflective) material. What effect will this have on the image of an object placed in front of the mirror ?

Suppose that the upper half of the concave mirror.s reflecting surface as shown in figure is covered with an opaque (non-reflective) material. What effect will this have on the image of an object placed in front of the mirror ?

The distance of an object from a spherical mirror is equal to the focal length of the mirror. Then the image:

Focal length of plane mirror is ......

Focal length of concave mirror is f and ratio of heights of object to image for an object at x distance from mirror is .....

Two plane mirrors at an angle such that a ray incident on a mirror undergoes a total deviation of 240^(@) after two reflections:

If a ray of light is incident on a plane mirror at an angle of 30^@ , then deviation produced by a plane mirror is .......

Suppose that the lower half of the concave mirror’s reflecting surface in Fig. 9.5 is covered with an opaque (non-reflective) material. What effect will this have on the image of an object placed in front of the mirror?
