Answer 1

Answer:

HIThe refraction index, n, of a transparent medium is defined as the ratio of speed of light in vacuum to the speed of light in that medium. The formula is n=vc. where the speed of light c=3×108m/s and v is the speed of light in the desired medium which is given as v=2. 4×108m/s.
