Challenge Problems
Push your limits with advanced challenges
Consider a double-slit experiment where the slits are 0.5 mm apart and the distance to the screen is 2 m. If the wavelength of light is 600 nm, find the distance between the first and second bright fringes.
💡 Hint: Set m=1 for the first fringe and m=2 for the second fringe.
Explain why polarized sunglasses reduce glare. What physics principles support this?
💡 Hint: Consider the orientation of light waves in relation to how they reflect off surfaces.
