Example Problems and Solutions
Here are a few examples of the types of problems and their solutions that can be found in this edition:
1. Problem: A ray of light strikes a glass surface at an angle of 30 degrees. What is the angle of refraction if the refractive index of glass is 1.5?
- Solution: Using Snell's law:
- n1 sin(θ1) = n2 sin(θ2)
- Assuming n1 (air) = 1.0, n2 (glass) = 1.5, and θ1 = 30 degrees:
- 1.0 sin(30) = 1.5 sin(θ2)
- This leads to sin(θ2) = (0.5 / 1.5) = 0.333, and thus θ2 = arcsin(0.333) ≈ 19.5 degrees.
2. Problem: Calculate the focal length of a concave lens with a radius of curvature of 20 cm.
- Solution: Using the lens maker's formula:
- 1/f = (n - 1) (1/R1 - 1/R2)
- For a concave lens, R1 is negative, and R2 is positive:
- Assume n = 1.5, R1 = -20 cm, R2 = ∞.
- Therefore, 1/f = (1.5 - 1) (1/(-20) - 1/∞) = 0.5 (-1/20) = -0.025, so f = -40 cm (the lens is diverging).
3. Problem: In Young's double-slit experiment, if the distance between the slits is 0.5 mm and the screen is 2 m away, calculate the distance between the first and second bright fringes for light of wavelength 500 nm.
- Solution: Using the formula for fringe spacing:
- Δy = (λL) / d
- Here, λ = 500 nm = 500 x 10^-9 m, L = 2 m, and d = 0.5 x 10^-3 m.
- Δy = (500 x 10^-9 2) / (0.5 x 10^-3) = 0.002 m or 2 mm.
