The refracted ray remains same frequency after refraction why?
Explanation of why the refracted ray remains the same frequency after refraction:

When a light wave travels from one medium to another, it changes its speed and direction. The phenomena is known as refraction. The frequency of the light wave remains constant upon refraction. There are several reasons why this happens.

The Nature of Light Waves:

Light is a form of electromagnetic radiation that travels in waves. Each wave has a certain frequency that determines the color of the light. The frequency is the number of waves that pass a point in a second. This frequency remains the same regardless of the medium the light wave travels through. Therefore, when a light wave enters a new medium, its frequency remains the same.

The Conservation of Energy:

Another reason why the frequency of a light wave remains constant upon refraction is the conservation of energy. The energy of a light wave is proportional to its frequency. Therefore, if the frequency were to change during refraction, the energy of the wave would also change. However, energy cannot be created or destroyed; it can only be transferred from one form to another. Therefore, the frequency of the light wave must remain constant for the energy of the wave to remain constant as well.

The Conservation of Momentum:

The conservation of momentum is another reason why the frequency of a light wave remains constant upon refraction. When a light wave enters a new medium, its direction changes. However, the momentum of the wave must remain constant. If the frequency were to change, the momentum of the wave would also change. Therefore, the frequency of the light wave must remain constant for the momentum of the wave to remain constant as well.

Conclusion:

In conclusion, the frequency of a light wave remains constant upon refraction because of the nature of light waves, the conservation of energy, and the conservation of momentum. These principles ensure that the energy and momentum of the wave remain constant, and that the frequency must remain constant as well.

Bcz frequency is source dependent..it changes only after changing the source. ...

Similar Class 12 Doubts

Read the following text and answer the following questions on the basis of the same:Negative Refractive Index: One of the most fundamental phenomena in optics is refraction. When a beam of light crosses the interface between two different materials, its path is altered depending on the difference in the refractive indices of the materials. The greater the difference, the greater the refraction of the beam. For all known naturally occurring materials the refractive index assumes only positive values. But does this have to be the case?In 1967, Soviet physicist Victor Veselago hypothesized that a material with a negative refractive index could exist without violating any of the laws of physics.Veselago predicted that this remarkable material would exhibit a wide variety of new optical phenomena. However, until recently no one had found such a material and Veselago’s ideas had remained untested. Recently, meta-material samples are being tested for negative refractive index. But the experiments show significant losses and this could be an intrinsic property of negativeindex materials.Snell’s law is satisfied for the materials having a negative refractive index, but the direction of the refracted light ray is ‘mirror-imaged’ about the normal to the surface.There will be an interesting difference in image formation if a vessel is filled with “negative water” having refractive index – 1.33 instead of regular water having refractive index 1.33.Say, there is a fish in a vessel filled with negative water. The position of the fish is such that the observer cannot see it due to normal refraction since the refracted ray does not reach to his eye.But due to negative refraction, he will be able to see it since the refracted ray now reaches his eye.Q. Which of the following is the intrinsic property of negative-index materials?
