Question

ASSERTION: WHEN LIGHT TRAVELS FROM ONE MEDIUM TO ANOTHER, THE DIRECTION OF PROPAGATION OF LIGHT IN SECOND MEDIUM CHANGES.REASON: LIGHT TRAVELS WITH DIFFERENT SPEEDS IN DIFFERENT MEDIUMS 

A) BOTH ASSERTION AND REASON ARE RIGHT, AND REASON IS CORRECT EXPLAINATION OF ASSERTION

B) BOTH ASSERTION AND REASON ARE RIGHT, AND REASON IS NOT THE CORRECT EXPLAINATION OF ASSERTION

C) ASSERTION IS TRUE BUT REASON IS FALSE*

D) ASSERTION IS FALSE BUT REASON IS TRUE

​

Answer 1

Answer:

both are true

Explanation:

yes both are true just mark it

Answer 2

The correct option is A) Both assertion and reason are right, and reason is correct explanation of assertion.

Assertion: When light travels from one medium to another, the direction of propagation of light in the second medium changes.

• As the light moves from one medium to another, its direction changes.
• The light bends towards the normal while travelling from rarer to denser medium.
• And light bends away from the normal while travelling from denser to rare medium.

Reason: Light travels at different speeds in different mediums.

• The speed of light varies in different mediums.
• The speed of light is more in rare medium while it is less in the denser medium.
• This is the reason why light bends while travelling from one medium to another.

Thus, the reason statement correctly explains the assertion statement.
