Question

p: light Ray passing along through the principle axis is unsecured Q: light light Ray passing through the focus is undeviated which is correct​

Answer 1

Answer:

Light ray passing through the focus is undeviated is correct

Answer 2

both P,Q are incorrect

To find:

P: light ray passing along the principal axis is undeviated

Q: light ray passing through the focus is undeviated

which of the following is correct?

a) both P,Q are correct

b) both P,Q are incorrect

c) P is correct, Q is incorrect

d) P is incorrect Q is correct​

Explanation:

• option b is the correct answer
• Ray passing through the optic centre of the lens is non-deviated.

• This is a point on a lens's principal axis where light passes through without deviating.
• A ray of light passing through optic centre the undergoes no refraction, meaning it passes straight through.
• hence, option (b) both P,Q are incorrect
