Question

the absolute refractive index of Ruby is 1.7 find the speed of light in Ruby the speed of light in vacuum is 3 into 10 raise to power 8 M per second

Answer 1

Answer:

Speed of light in ruby = 1.765 × 10^8  m/sec

Step by step explaination:

Refractive index of any material is given as

Refractive index (n) = Velocity light in Vacuum ÷ Velocity of light in the medium.

For Ruby, Refractive index n(R) can be calculated as

n(R) = Speed of light in vacuum ÷ Speed of light in Ruby

∴ Speed of light in Ruby V(R) = Speedof light in vacuum ÷ Refractive index n(R)

∴ V(R) = ( 3×10^8 ) ÷ 1.7

∴ V(R) = 1.765 × 10^8 m/sec

∴ Speed of light in ruby = 1.765 × 10^8  m/sec
