Correct Answer: Option B
Explanation:
n = \(\frac{\text{speed in air}}{\text{speed in glass}}\)
1.5 = \(\frac{3\times10^4}{\text{speed in glass}}\)
speed in glass = 2 x 108ms-1
n = \(\frac{\text{speed in air}}{\text{speed in glass}}\)
1.5 = \(\frac{3\times10^4}{\text{speed in glass}}\)
speed in glass = 2 x 108ms-1
