Questions & Step-by-Step Solutions

What is the critical angle for total internal reflection when light travels from water (n = 1.33) to air (n = 1)?
  • Step 1: Identify the refractive indices. For water, n1 = 1.33 and for air, n2 = 1.
  • Step 2: Use the formula for critical angle: sin(θc) = n2/n1.
  • Step 3: Substitute the values into the formula: sin(θc) = 1/1.33.
  • Step 4: Calculate the value of sin(θc): sin(θc) ≈ 0.7519.
  • Step 5: Use the inverse sine function to find θc: θc = sin⁻¹(0.7519).
  • Step 6: Calculate θc, which is approximately 53.1 degrees.
