Physics-Huygens Principle
NEET Physics Huygens Principle MCQ Question
Type: MCQ-numerical-Medium-Class 12
When a wavefront enters a second medium with speed v2 from a medium with speed v1, what is the ratio of the sine of the angle of incidence (i) to the sine of the angle of refraction (r)?
A
v1/v2
B
v2/v1
C
v1 * v2
D
v2 - v1
Correct Answer
Option A
Detailed Explanation
According to the relationship derived using Huygens Principle, sin(i)/sin(r) = v1/v2, where v1 and v2 are the wave speeds in the first and second medium respectively.
