Challenge Problems
Push your limits with advanced challenges
In a double-slit experiment, if the wavelength used is 550 nm and the distance between the slits is 0.5 mm, calculate the position of the fourth dark fringe observed on a screen 1.5 meters away.
💡 Hint: Consider how far the pattern spreads when light reaches the screen.
A coherent light source produces 50 fringes in a 2 m path. Find the wavelength used if the slit distance is 0.4 mm.
💡 Hint: Use the known values to solve step-by-step.
