Respuesta :
The angle of refraction of a ray of light that enters a diamond from air is 7.3°.
What is Snell's law?
It states that the ratio of sine of angle of incidence and angle of refraction is equal to the refractive index of second medium to the first medium.
sini/sinr =n₂/ n₁
Given the angle of incidence i = 18 degrees, refractive index of air n₁ =1, refractive index of diamond n₂= 2.419 then, angle of refraction
sin r = 1 x sin 18/2.419
sin r = 0.1277
r = 7.3°
Thus, the angle of refraction of a ray of light that enters a diamond from air is 7.3°
