Question

what will be angle of refraction if angle of incidence is 30 degree.
the answer is not 30 degree.

Answer 1

Hello mate,

Focus on the wod , its REFRACTION .

So obivously the angle of refraction will not be the same.

You need the refractive index.

Then follow the Snell's law i.e

$\frac{Sin i}{Sin r}=Refractive index$

Hope this helps you.

Please mark me the brainliest.
