Question
You can produce a spectrum by placing a tray of water inbright sunlight. Lean a pocket mirror against the insideedge of the tray and adjust it until a spectrum appearson the wall or ceiling. Aha! You’ve produced a spectrumwithout a prism.
Step 1
When light falls on water, it refracts, or bends, because of the change in medium. This is due to the fact that light travels at different speeds in different mediums. Show more…
