Concave Mirror

Q.

Name the mirror that can give an erect and enlarged image of an object.

Q.

Define the principal axis.

Q.

When a concave mirror is used as a shaving mirror, where is the face of a man about the focus of the mirror? State the characteristics of the image seen.

Q. Using mirror formula show that : 1.An object placed between focus and centre of curvature of a concave mirror produces a real image beyond the centre of curvature 2.for an object placed between the pole and the focus of a concave mirror, the image is always virtual and enlarged 3.a convex mirror always produces a virtual image independent of the location of the object 4.the virtual image produced by a convex mirror is always diminished in size and is located between the focus and the pole of the mirror

Q.

In which of the following cases, a bright image is produced

1. the image formed by a concave mirror

2. the image formed by a convex lens

3. the image formed due to total internal reflection of light

Q. Choose the wrong statement

1. A concave mirror can be used to concentrate the incident rays at a particular point.
2. A concave mirror can form a magnified virtual image.
3. A convex mirror can be used to concentrate the incident rays at a particular point.
