Question

the speed of light in air is 3 into 10 to the power 8 metre per second and the speed of light in water is 2.26 into 10 to the power 8 metre per second calculate the refractive index of water

Answer 1

n = 3/2.26=300/226=150/113=1.33

Answer 2

Answer:

1.32743363

Step-by-step explanation:

Speed of light in air = 3 × 10^8

Speed of light in water = 2.26 × 10^8

Refractive index of water = Speed of light in air/speed of light in water

= (3 × 10^8)/(2.26 × 10^8)

= 1.32743363

Hope this helps...:)
