Experiments

🔍 Explore
Investigate interference and diffraction in water, sound and light waves.

🎮 Try It
Change frequency and amplitude, turn on a second source and vary its separation. In Slits mode, compare one and two slits and change their width. In Diffraction mode, switch between round and square apertures and resize them.

🎯 Your Mission
Predict how making a single slit narrower will change the pattern beyond the barrier. Test at two widths while keeping frequency fixed, and use the amplitude display as evidence.

🌍 Real-World Connection
Sound can spread through a doorway because waves diffract around openings.
