Questions with solutions
Q1 — Reflection & Refraction · medium · theory
According to the laws of reflection, the angle of incidence is:
A. less than the angle of reflection
B. greater than the angle of reflection
C. equal to the angle of reflection ✓ Correct
D. always 90°
Solution: The angle of incidence equals the angle of reflection, both measured from the normal.
Q2 — Reflection & Refraction · hard · numerical
A ray of light strikes a plane mirror making an angle of 30° with the mirror surface. The angle of reflection (measured from the normal) is:
A. 120°
B. 30°
C. 90°
D. 60° ✓ Correct
Solution: The angle of incidence from the normal $= 90° - 30° = 60°$, so the angle of reflection is also 60°.
Q3 — Reflection & Refraction · medium · theory
When light travels from air into a denser medium such as glass, it bends:
A. away from the normal
B. along the surface
C. back into air
D. towards the normal ✓ Correct
Solution: On entering a denser medium light slows down and bends towards the normal (refraction).
Q4 — Reflection & Refraction · medium · theory
A pencil placed in a glass of water appears bent at the water surface because of:
A. dispersion of light
B. absorption of light
C. refraction of light ✓ Correct
D. reflection of light
Solution: Light from the submerged part bends as it leaves the water, making the pencil appear bent.
Q5 — Reflection & Refraction · hard · theory
The speed of light is greatest in:
A. diamond
B. vacuum ✓ Correct
C. glass
D. water
Solution: Light travels fastest in vacuum; denser media (water, glass, diamond) slow it down.
