NEET Physics Huygens Principle MCQ Question
Using Huygens' Principle, if a wave travels from a medium with speed v1 to another with speed v2 such that v2 = 0.5v1, what is the ratio of the sine of the angle of incidence to the sine of the angle of refraction?
2:1
1:2
1:1
4:1
Correct Answer
Detailed Explanation
According to Huygens' Principle, the ratio of the sine of the angle of incidence to the sine of the angle of refraction is equal to the ratio of the speeds of the waves in the two media. Since v2 = 0.5v1, the ratio is 2:1.
