Question

The speed of light in a certain glass is 1.8×10 m/s define refractive index ans the si uni​

Answer 1

Answer:

The refractive index is given by

n=c/v

Where n is the refractive index

c is the speed of light in vacuum

v is the speed of light in that medium

It is given that speed of light in a medium(v)is1.8∗1000=1.8∗10

3

m/s

Speed of light in vacuum=3∗10

3

m/sec

n=3∗10

3

/1.8∗10

3

n=3/1.8

=1.6666

=1.67
