Question

10. Among the following the one which is not the case with the image fomed by a concave mirror is
a) it may be erect or inverted
b) it may be magnified or diminished
c) it may be real or virtual
d) real image may be between pole and focus​

Answer 1

Answer:

d) is the correct option.....

Answer 2

The correct option of the following question is (d)

• When light from infinity strikes the concave lens, the virtual and erect image is formed at focus. The size of the image formed is very small than that of the size of the object.
• When the object is placed at beyond infinity, the image is formed between F1 and optical centre. The image formed is virtual and erect, and size of the image is diminished.
• So, in case of concave lens, image formed maybe erect or inverted. It can also be magnified or diminished, and it may be real or virtual.
• In case of concave lens, the virtual image will be formed between pole and focus.

So, option (4) is wrong, which is real image may be formed between pole and focus.
