Challenge Problems
Push your limits with challenges.
Question 1
A light wave has a wavelength of 500 nm in a vacuum. It enters a medium with a refractive index of 1.5. Calculate the new wavelength inside the medium.
💡 Hint: Use the relationship between wavelength and refractive index.
Question 2
In a Young's double-slit experiment, the fringe spacing on a screen is 0.5 cm when the wavelength is 600 nm. If the wavelength is changed to 700 nm, how will the fringe spacing change?
💡 Hint: Consider the relationship between fringe spacing, wavelength, and distance to the screen.
