Question

Assertion: A lens is when two transparent mediums are fused with each other.


Reason: One surface out of the two should be spherical.



(a) If Assertion and reason are correct and reason is the correct explanation of assertion. (b) If assertion is correct and reason is false. (c) If assertion is incorrect and reason is correct. (d) If assertion and reason are incorrect.​

Answer 1

Answer:

Correct option is

C

Assertion is correct but Reason is incorrect

If the refractive index of two medium is same then light wave will travel in a straight line without bending.

According to Snell's law n

1

sinθ

1

=n

2

sinθ

2

n

1

=n

2

⟹θ

1

=θ

2

So we can see that the bending of light will depend upon the refractive index of medium.
