Question

HOW TO MEASURE THE ANGLE OF REFRACTION FOR ANY ANGLE OF INSIDENCE. FOR EG LIGHT SRIKES AT 50 ° FIND ANGLE OF INSIDENCE​

Answer 1

For air, n1 = 1.00003; for water, n2 = 1.3330

Given: θ2 = 40 degrees, then

θ1 = sin^-1[(n2/n1)sin θ2] = sin^-1[(1.3330/1.0003)sin (40)] = 58.93 degrees

Answer 2

Answer:hi buddy its very simple

Step-by-step explanation:

First the normal is 90°

Now angle is 50°

So our incidence angle = 90-50= 40°

So angle of emergence also =40°
