Question

A 330 nm lightwave travels through a piece of quartz (nı = 1.544) and enters into a pool of water (n2 - 1.33). If the lightwave hits the interface at 01 = 15° angle with the normal (see picture) at what angle, 02, will the light refract into the water? n n2 O 17.59 O 0.75° 23.6° 0.22°

Answer 1

Liefractive index of medium 1, n = 1:544 Angle of incidence, ex = '15° Mefractive index of medium2, n = 1:33 Angle of refraction, O = ? Acconding to shell's law of refraction n, sind, n, sind sin Oz = n, sind, (7-544) sin(159) => sin O₂ = 0.3005 O₂ = sin(0.3005) 10 = 17.5° Answer. n (1.33)

Therefore angle of refraction is 17.5° ( option A).
