Answer #1

According to snell's law we can write

n1 sin 65 = n2 sin 80

for air n1 = 1

==> refractive index of diamond n2 = n1 sin 65 / sin 80

= 1 * 0.920

= 0.920

    In a diamond, the index of refraction for violet light (λ = 400 nm) is 2.46, and for red light (λ = 700 nm) it is 2.41. A ray of light traveling through air strikes the diamond surface at an angle of 42.8° to the normal. What is the angular separation between these two colors of light in the refracted ray? A. 0.72° B. 0.35° C. 0.96° D. 1.16°

  • A beam of white light is incident on the surface of a diamond at an angle...

    A beam of white light is incident on the surface of a diamond at an angle θa. (Figure 1) Since the index of refraction depends on the light's wavelength, the different colors that comprise white light will spread out as they pass through the diamond. For example, the indices of refraction in diamond are nred=2.410 for red light and nblue=2.450 for blue light. Thus, blue light and red light are refracted at different angles inside the diamond, as shown in...
