Question

Draw a ray diagram to show the formation of the image, when the object is placed anywhere in front of a concave lens.

State the signs and values of magnifications in the above mentioned case.

Answer 1

When an object is placed anywhere in front of a concave lens.

Since the image formed is virtual and erect, the sign of magnification will be positive. Moreover, the image formed is diminished; therefore, the absolute value of magnification will be less than one.
