When monochromatic light travels from one medium to another

Asked by admin @ 17/08/2021 in Physics viewed by 284 People

When monochromatic light travels from one medium to another its wavelength changes but frequency remains the same. Explain. [NCERT Example, Delhi 2011]

Answered by admin @ 17/08/2021

Answer:

Frequency is the characteristic of the source. That is why it remains the same. But wavelength is charactristic of the medium. So wavelength and veloctiy both change.
