NEET Physics Refraction Match the Following Question
Match Column-I with Column-II.
| Column-I | Column-II |
|---|---|
| (a) Critical angle | (i) n 12 = 1/sin i c |
| (b) Total internal reflection | (ii) Light grazing the surface |
| (c) Angle of incidence | (iii) Refraction not possible |
| (d) Snell's law | (iv) sin i / sin r = constant |
a-i, b-iii, c-ii, d-iv
a-ii, b-i, c-iii, d-iv
a-iv, b-ii, c-i, d-iii
a-iii, b-iv, c-i, d-ii
Correct Answer
Detailed Explanation
The critical angle is defined by the equation n 12 = 1/sin i c, where i c is the critical angle. Total internal reflection occurs when the angle of incidence exceeds the critical angle, making refraction impossible. Snell's law states that sin i / sin r = constant, which relates the angles of incidence and refraction.
