What is the magnification produced by a rear view mirror fitted in vehicles?

A vertical ray of light strikes the horizontal surface of some water:

1. What is the angle of incidence?
2. What is the angle of refraction?

The linear magnification produced by a spherical mirror is +3. Analyse this value and state the (i) type of mirror and (ii) position of the object with respect to the pole of the mirror. Draw ray diagram to show the formation of image in this case.

Name the lens which always forms a virtual image of an object.

Does the incident and emergent ray coincide in the process of refraction through glass slab? Give reason.

What do you mean by laterally inverted?

Draw a ray diagram to show the formation of a real magnified image by a convex lens. (In your sketch the position of object and image with respect to the principal focus of lens should be shown clearly).

If a ray of light is incident on a plane mirror such that it makes an angle of 30with the mirror, then will be the angle of reflection?

An object is placed at the following distance from a convex lens of focal length 15cm:

1. 35cm
2. 30cm
3. 20cm
4. 10cm

Which position of the object will produce:

1. A magnified real image?
2. A magnified virtual image?
3. A diminished real image?
4. An image of same size as the object?
