Question

Write the approximate values of speed of light in (i) air and (ii) glass. Use these values to calculate the refractive index of glass with respect to air.

Numerical

Solution

(i) Speed of light in air = 3 × 10ms-1
(ii) Speed of light in glass = 2 × 10ms-1

Refractive index of glass with respect to air

= `"Speed of light in air"/"Speed of light in glass"`

= `(3xx10^8)/(2xx10^8)`

= `3/2`

= 1.5
