Challenge Problems

Push your limits with advanced challenges

Challenge 1 Hard

Calculate the angle of constructive interference if two waves with a wavelength of 500 nm create a pattern at a distance of 2 m from the slits and are separated by 0.02 m.

💡 Hint: Utilize the fundamental equation for constructive interference.

Challenge 2 Hard

In a sound interference scenario, two speakers emit sound waves at a frequency of 440 Hz. If one speaker is 2 meters closer to a listener than the other, is there interference? What type?

💡 Hint: Calculate the wavelength first!
