If an object is placed at a distance of 10 cm in from of a plane mirror, how far would it be from its image?
When a ray of light passes from air into glass, is the angle of refraction greater than or less than the angle of incidence?
Light travels more quickly through water than through glass.
If a ray of light passes from glass into water, which way will it bend : towards the normal or away from the normal?
Name the phenomenon due to which a pencil partly immersed in water and held obliquely appears to be bent at the water surface.

What is the angle of refraction?
A ray of light passes from medium 1 to medium 2. Which of the following quantities of the refracted ray will differ from that of the incident ray: Speed, intensity, frequency, wavelength?
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
What is refractive index?
Assertion: The air bubble shines in water.
Reason: Air bubble shines due to the refraction of light.
Which is optically denser out of the two medium M1& M2 having the refractive indices = 1.71 and 1.36 respectively?
