Question

(1) Which is optically denser: air or water give a reason?
(2) Out of air or glass, which is optically rarer? give a reason

please help me, everyone please don't give unesseary answers like chats I am not interested
thank u but please help

Answer 1

Answer:

1) Water is more denser than air

2)out of air

Explanation:

because in the water the molecules are more packed rather than air

Speed of light in air is more than speed of light in glass, which means air is optically rarer than glass.

Answer 2

1.Water

2.air

the speed of light in water is more than its speed in a medium of glass. This suggests that out of the two mediums, glass and water, glass is the optically denser one.

When water travels through water, its speed gets reduced. Hence, it is a optically denser medium. Speed of light in air is more than speed of light in water, which means water is optically denser than air.
