When monochromatic light travels from one medium to another its wavelength changes but frequency remains the same. Explain. |
|
Answer» Solution :Atoms (of the second medium) oscillate with the same (INCIDENT LIGHT) frequency and in turn, EMIT light of the same frequency. Alternatively, Frequency of light may be viewed as a property of the source and not of the medium. Alternatively, From Huygen.s principle, we FIND that `(v_(1))/(lambda_(1))=(v_(2))/(lambda_(2))=n`(Frequency) Hence frequency remains the same. |
