Reason: Image formed by a lens is real if the image is formed in the direction of ray of light with respect to the lens. ​

Answer 1

Assertion:

Image formed by concave lens is not always virtual.

No , Assertion is not correct

This is because , irrespective of the position of the object , a concave lens always produces a virtual image which share the following common characteristics :

• Image is upright
• Image is diminished
• Image is erect

The virtual image from concave lens is always produced against the direction of light with respect to the lens.

Reason:

Image formed by a lens is real if the image is formed in the direction of ray of light with respect to the lens.

• Image is inverted
• Image can be Magnified/Diminished.
