NEET Physics Refraction MCQ Question
A ray of light passes from a medium of refractive index 1.5 to a medium of refractive index 1.2. If the angle of incidence is 30°, what is the angle of refraction?
36.87°
24.62°
41.81°
19.47°
Correct Answer
Detailed Explanation
Using Snell's Law, n1 * sin(i) = n2 * sin(r), where n1 = 1.5, n2 = 1.2, and i = 30°. Solving gives sin(r) = (1.5/1.2) * sin(30°) = 0.75, so r = 36.87°.
