Question

1. The lateral magnification of an object by a spherical mirror is positive. Which is true?

The image must be a real image.

The image could be either a real or virtual image.

The image must be a virtual image.

2. Which is true about spherical mirrors?

A convex mirror has a positive focal distance. A concave mirror has a negative focal distance.

A convex mirror has a negative focal distance. A concave mirror has a positive focal distance.

A convex mirror has a negative focal distance. A concave mirror can have a negative focal distance or a positive focal distance, depending on the object distance.

3. Which is true about a convex spherical mirror?

It produces a virtual image when the object is inside the focal point and a real image when the object is outside the focal point.

It produces a real image when the object is inside the focal point and a virtual image when the object is outside the focal point.

It always produces a virtual image.

It always produces a real image.

4. Which is true about a concave spherical mirror?

It produces a virtual image when the object is inside the focal point and a real image when the object is outside the focal point.

It produces a real image when the object is inside the focal point and a virtual image when the object is outside the focal point.

It always produces a virtual image.

It always produces a real image.
