A ray of light strikes a mirror at an angle of 53 degrees to the normal.(adsbygoogle = window.adsbygoogle || []).push({});

A) what is the angle of reflection?

Ans: 53 degrees

B) what is the angle between the incident ray and the reflected ray?

Ans: 53+53 = 106 degrees

C) A ray of light has an angle of incidence of 30 degres on a block of quartz and an angle of refraction of 20 degrees. What is the index of refraction for this block of quartz?

Ans: Nr = (1.54) (sin 30) / (sin20) = 2.25

are the above answers correct?

thanks
