If a ray of light traveling in air strikes the surface of an amethyst crystal (n 1.553) at 35° toward the normal, what is the angle of incidence

Respuesta :

Answer:

Angle of incidence is given as

[tex]i = 63 ^o[/tex]

Explanation:

As per law of refraction of light we know that

[tex]n_1 sin i = n_2 sin r[/tex]

here we know that

angle of refraction is "r"

[tex]r = 35^o[/tex]

now we have

[tex]1 sin i = 1.553 sin35[/tex]

[tex]sin i = 0.89[/tex]

[tex]i = 63 ^o[/tex]
