In refraction, light waves are bent on passing from one medium to second medium because, in the second medium
- A frequency is different
- B speed is different
- C coefficient of elasticity is different
- D amplitude is smaller
Answer & Solution
Correct Answer
(B) speed is different
Step-by-step Solution
Detailed explanation
The bending of light in passing from one medium to another is due to refractive index of second medium with respect to first.
The refractive index is related to the speed of light in two media as
\({ }_{1} \mu_{2}=\frac{\text { Speed of light in first medium }}{\text { Speed of light in second medium }}\)
Thus, on passing from one medium to second medium, the speed of light different.
The refractive index is related to the speed of light in two media as

Thus, on passing from one medium to second medium, the speed of light different.
