Calculate speed of light in water of refractive index 4/3. Given speed of light in air = 3×10^8 m/s |
| Answer» We know that,Refractive index=speed of light in air/speed of light in other mediumSo, let speed of light in other medium be a4/3= 3×10^8/aa=3×10^8×3/4a=9×25×10^6a=225×10^6a=2.25×10^8m/sHope it helps.... | |
