Question

What will the angle of refraction be for a ray of light passing from air into a sodium chloride crystal if the angle of incidence is 60.0°? The index of refraction of sodium chloride is 1.53.

Answer 1

A. 13°B. 22°C. 34°D. 42°E. 48°

Answer 2

Do u know what Snell's law is ? It says\[\sin i /sinr =\mu \]
where i is angle of incidence ,r is angle of refraction and μ is refractive index.

That is all in this question. Put i and μ and find r.

ok thanks
