Q
Q: What is the critical angle for total internal reflection when light travels from glass (n = 1.5) to air (n = 1)?
Solution:
The critical angle θc is given by sin(θc) = n2/n1. Thus, θc = sin^(-1)(1/1.5) ≈ 41.8 degrees.
Steps: 6
Show Steps
Step 1: Identify the refractive indices of the two materials. For glass, n1 = 1.5 and for air, n2 = 1.
Step 2: Use the formula for the critical angle, which is sin(θc) = n2/n1.
Step 3: Substitute the values into the formula: sin(θc) = 1/1.5.
Step 4: Calculate 1/1.5, which equals approximately 0.6667.
Step 5: Use the inverse sine function to find θc: θc = sin^(-1)(0.6667).
Step 6: Calculate the angle using a calculator, which gives θc ≈ 41.8 degrees.
