A) the frequency is different
B) the coefficient of elasticity is different
C) the speed is different
D) the amplitude is smaller
Correct Answer: C
Solution :
The refractive index is related to the speed of tight in the two media as given below \[_{1}{{\mu }_{2}}=\frac{\text{speed}\,\,\text{of}\,\,\text{light}\,\,\text{in}\,\,\text{first}\,\,\text{medium}}{\text{speed}\,\,\text{of}\,\,\text{light}\,\,\text{in}\,\,\text{second}\,\,\text{medium}}\] or speed of light in second medium \[=\frac{\text{speed}\,\,\text{of}\,\,\text{light}\,\,\text{in}\,\,\text{first}\,\,\text{medium}}{_{1}{{\mu }_{0}}}\] where \[_{1}{{\mu }_{2}}\] is refractive index of second medium relative to the first medium. Hence, we see that on passing through another medium, speed of light changes due to which it bends.You need to login to perform this action.
