प्रश्न
A ray of monochromatic light propagating in the air is incident on the surface of the water. Which of the following will be the same for the reflected and refracted rays?
विकल्प
Energy carried
Speed
Frequency
Wavelength
उत्तर
Frequency
Explanation:
The interaction of light with the atoms at the surface of separation results in both reflection and refraction. You may think of these atoms as oscillators. Such atoms are made to vibrate at the frequency of light when light strikes them. Both the reflected and refracted lights have the same frequency as the incident light since the light output by these charged oscillators is equal to their own oscillation frequency.
