What is the cause of refraction of light when it passes from one medium to another?
The laws of reflection hold true for ______.
Write scientific reason.
The sun appears on the western horizon for some time after sunset.
Assertion and reasoning type
- Assertion: If the refractive index of the medium is high (denser medium) the velocity of the light in that medium will be small
- Reason: Refractive index of the medium is inversely proportional to the velocity of the light

Assertion: The air bubble shines in water.
Reason: Air bubble shines due to the refraction of light.
