प्रश्न
Which property of light does not change when it travels from one medium to another?
The property of light which does not change, when it travels from one medium to another is ______.
पर्याय
Velocity
Wavelength
Amplitude
Frequency
उत्तर १
Frequency
Explanation:
When the light passes from one medium to another, the property called refraction occurs. This refraction is the bending of light at the interface of two mediums. This bending would further result in a change in velocity, amplitude and wavelength. The frequency of the light wave is a parameter of the source that it emits from. It does not depend on the medium of propagation.
उत्तर २
The property of light which does not change, when it travels from one medium to another is frequency.
