Challenge Problems
Push your limits with advanced challenges
A monochromatic light source produces interference on a screen 1.2m away from the pinholes. If the distance between the pinholes is 0.4mm and the fifth bright fringe is 3cm from the central maximum, calculate the wavelength.
💡 Hint: Convert units as necessary to ensure consistency.
In a set of experiments with red and green lasers producing interference, the red laser (λ=650 nm) shows fringes spaced wider apart compared to the green (λ=532 nm). Explain why.
💡 Hint: Consider how wavelength affects the calculation of fringe positions.
