Answer» ong>Answer:The 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= v c .
where the speed of light c=3×10 8 m/s and v is the speed of light in the desired medium which is given as v=2.4×10 8 m/s.
Therefore, n= 2.4×10 8 m/s 3×10 8 m/s =1.25.
Hence, the REFRACTIVE index of the transparent medium is 1.25 Explanation: |
