Answer to Question #197213 in Optics for Daniel

Question

What of using this method ???

solution

μ = sin i ÷ sin r→

1.5 = sin (60 / sin r →

1.5 =0.8660 / sin r →

1.5 ★ sin r = 0.866→

sin r = 0.866/1.5→

sin r = 0.5773→

r = sin inverse of 0.5773→

r = 35.2.

Answer 1

Answer

This is snell's law.

"I" Is incident angle.

And "r" is refraction angle.

Here $\mu$ is is the refractive index of medium through which light is passing from the air.

And at last refraction angle is calculated.
