Description
๐ Explore
Investigate interference and diffraction in water, sound and light waves.
๐ฎ 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.
๐ฏ 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.
๐ Real-World Connection
Sound can spread through a doorway because waves diffract around openings.
