The angle between the incident ray and the ray reflected from the plane mirror is 70°. The angle of incidence will be:

1. 70°
2. 30°
3. 35°
4. 90°

The image formed by a plane mirror is:

1. virtual and inverted
2. virtual and of same size
3. real and inverted
4. real and of same size

The angle of incidence on a plane mirror is 30°. The angle between the incident ray and the reflected ray is:

1. 30°
2. 15°
3. 60°
4. 90°

The property due to which a light ray striking a surface is returned back into the same medium is called:

1. refraction
2. reflex action
3. reflection
4. regression
