When monochromatic light travels from one medium to another its wavele

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