A concave mirror cannot from

Focal length of a concave mirror is

State two uses of a concave mirror.

A kid of height 1.1 ft is sleeping straight between focus and centre of curvature along the principal axis of a concave mirror of small aperture. His head is towards the mirror and is 0.5 ft from the focus of the mirror. How a plane mirror should be placed so that the image formed by it due to reflected light from concave mirror looks like a person of height 5.5 ft standing vertically. Draw the ray diagram. Find the focal length of the concave mirror.

The shape of reflected wavefronts in case of reflection of plane wave front from concave mirror is

Mention one difference between reflection of light from a plane mirror and total internal reflection of light from a prism.

To construct a ray diagram we use two rays of light which are so chosen that it is easy to determine their directions after reflection from the mirror. Choose these two ras and state the path of these rays after reflection from a concave mirror . Use these two rays to find the nature and position of the image of an object plced at a distance of 15 cm from a concave mirror of focal length 10 cm.

Differentiate between the reflection of light from a plane mirror and that from a plane sheet of paper.

Draw a diagram showing the reflection of a light ray from a plane mirror. Label on it the incident ray, the reflected ray, the normal, the angle of incidence i and the angle of reflection r.

Radius of curvature of each mirror is R. 'O' is object. Consider first reflection from concave mirror. Consider only first three reflection. The distance of final image from convex mirror is
