Question

If the speed of licht in eis 210 m/s, what will be the
the reactive index of glass with respect
Skill​

Answer 1

Answer:

I am considering speed of light in material as

2*10^8(m/s)

we know that refractive index is given by

n = c/v,

where ,c is speed of light in vaccuum,

i.e,3*10^8(m/s),

v is the speed of light in given material,

therefore,

refractive index ,n = (3*10^8)/(2*10^8),

=> n = 1.5
