| List-I | List-II |
| Phenomenon | Characteristics |
| (A) Reflection | (I) Used for reducing glare |
| (B) Refraction | (II) Change in path when a light is incident on opaque medium |
| (C) Interference | (III) Change in path when a light is incident on transparent medium |
| (D) Polarisation | (IV) Light added to light to produce darkness |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 4
The correct answer is Option (4) → (A)-(II), (B)-(III), (C)-(IV), (D)-(I)
Each phenomenon is identified by what happens to the light at a surface or when waves combine.
(A) Reflection — this matches (II) Change in path when a light is incident on opaque medium. Light that cannot enter an opaque surface is sent back into the first medium.
(B) Refraction — this matches (III) Change in path when a light is incident on transparent medium. Light enters the transparent medium and bends because its speed changes.
(C) Interference — this matches (IV) Light added to light to produce darkness. Where two coherent waves meet in opposite phase they cancel, giving destructive interference (dark fringes).
(D) Polarisation — this matches (I) Used for reducing glare. Polaroid sunglasses block the partly polarised light reflected from shiny surfaces.
