Worksheet
  • 1.

    Multiple Choice

    1 pts•30 s

    What is the first law of refraction?

    Answer choices

    The incident ray and refracted ray are in different planes

    The incident ray, refracted ray, and normal lie in the same plane

    The angle of incidence equals the angle of refraction

    The refracted ray bends away from the normal

  • 2.

    Multiple Choice

    1 pts•30 s

    Identify the law that relates the angle of incidence and angle of refraction to the refractive indices of two media.

    Answer choices

    Newton’s law

    Snell’s law

    Law of reflection

    Pascal’s law

  • 3.

    Multiple Choice

    1 pts•30 s

    Which statement describes Snell’s law mathematically?

    Answer choices

    n₁ sin θ₁ = n₂ sin θ₂

    n₁ cos θ₁ = n₂ cos θ₂

    n₁ tan θ₁ = n₂ tan θ₂

    n₁ sin θ₁ = n₂ cos θ₂
