Question 1
What equation defines the location of bright fringes?
- Δx = nλ
- Δx = (n + 1/2)λ
- Δx = λ/n
- Δx = 2nλ
💡 Hint: Recall how constructive interference is defined.
Question 2
True or False: Dark fringes appear where constructive interference occurs.
- True
- False
💡 Hint: Think about the patterns created by wave interactions.

Challenge Problems
Push your limits with challenges.
Question 1
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.
Question 2
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.
