Answer: The angle of refraction is 32°

Explanation:

By snell law, we have that:

n₁*sen(θ₁) = n₂*sen(θ₂)

Where n₁ = 1.5

n₂ = 2.0

θ₁ = 45°.

then we want to find the angle of refraction.

1.5*sin(45°) = 2*sin(x)

x = Asin(1.5*sin(45°)/2) = 32°

The angle of refraction is 32.0 degrees

Refractive index and Shell's law

Snell’s Law describes how a ray of light will change direction as it passes from one medium into another, or as it is reflected from the interface between two media.

Snell's law states that:

  • n1 * Sinθi = n2 * Sinθr

where;

  • nA is refractive index of media A
  • θi is the angel of incidence in media 1
  • n2 is the refractive index of media 2
  • θr is the angle of refraction in media 2

Using the formula above

1.5 * sin 45 = 2.0 * sin r

sinr = 1.5 × sin 45/2

r = 32.0 degrees

Therefore, the angle of refraction is 32.0 degrees
