Best Answer

Ans. a. F

A convex mirror forms a virtual, erect and diminished image. So, we can’t obtain an enlarged image by a convex mirror.

b. T

The concave lens forms a virtual image which is erect and diminished. So, it is True.

c. T

The image obtained using a concave mirror can be real or virtual, enlarged and inverted. The image formed depends on the distance of object from the concave mirror.

d. F

Real images are the images which can be obtained on screen and virtual images are those which can’t be obtained on the screen. So, this statement is false.

e. F

Both real and virtual images can be obtained with the help of a concave mirror. The image formation depends on the distance of object from the mirror. So, this statement is false.
