Question

If a ray of light takes t1 and t2 times in two media of absoulte refractive indices u1 and u2 respectively to travel same distance,then

Answer 1

As the light travels between two medium it will face refraction.  

Explanation:

• Refraction is a phenomenon exhibited by light. This results due to changes in the velocity of light in different materials.

• This can be explained using Snell's Law.  

• The given formula of this law is n2sin i=n1 sin r.

• Meanwhile, n1 and n2 represent absolute refractive indices.

• These values are shown in regards to vacuum or air.

Answer 2

$\Huge \tt Refraction$
