Question

Wavelength Of A Light Decrease When Light Enters Into A Denser Medium From A Rarer Medium !

A. True
B. False

Answer 1

Answer:

...true..

When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases. Part of the wave travels faster for longer causing the wave to turn. The wave is slower but the wavelength is shorter meaning frequency remains the same.
