When light undergoes refraction, its frequencya)Increasesb)Remains samec)Decreasesd)Increases exponentiallyCorrect answer is option 'B'. Can you explain this answer?

Question

Answer

Light refracts as it passes through a material. It's direction changes, but it still passes through. Light travels at a maximum speed -- the speed of light in a vacuum, but when traveling in anything else it slows down. Different materials slow the speed of passing light at different rates. This property of matter is called the refractive index. When refracting, light doesn't change it's frequency, but since it changes it's speed, it must also change it's wavelength (it gets squished or elongated). Frequency, wavelength, and speed are all related, so if one property changes, another must as well.

Answer

Remains same

Answer

Due to wavelength is shorter

Answer

Frequency remains same for all type of medium because it is depends on the source not on the medium in it travel it will helpful for you

Answer

Yes..bcz it depends on the source not on the medium

Answer

Yes, Because frequency is the property of source, so it remains same.

Answer

Frequency does not depends on the incidant light

Answer

IMP Note::
1) FREQUENCY is the property of SOURCE
2) WAVELENGTH is the property of MEDIUM
(In case of refraction source doesn't change so frequency remains same, in case of reflection too for frequency)

Answer

It remains same bec. frequency depends only on source and don't  change during course of refraction

Answer

Frequency is the property of source , that's why frequency remains constant whenever refraction takes plce

Answer

I don't no

Answer

It always remains same

Answer

Explanation:

Refraction is the bending of light when it passes from one medium to another. It occurs due to the change in the speed of light as it travels from one medium to another. When light undergoes refraction, its frequency remains the same.

Refraction of light:
When light passes from one medium to another, such as from air to water or from air to glass, it changes its direction. This change in direction is called refraction. It occurs because the speed of light is different in different media. When light travels from a medium with a lower refractive index to a medium with a higher refractive index, it bends towards the normal (an imaginary line perpendicular to the surface of the interface). On the other hand, when light travels from a medium with a higher refractive index to a medium with a lower refractive index, it bends away from the normal.

Frequency of light:
The frequency of light refers to the number of complete cycles of the electromagnetic wave that pass a given point in one second. It is measured in hertz (Hz). The frequency of light determines its color, with higher frequencies corresponding to colors towards the violet end of the spectrum and lower frequencies corresponding to colors towards the red end of the spectrum.

Effect of refraction on frequency:
When light travels from one medium to another, its speed changes, but its frequency remains constant. According to the wave equation, the speed of a wave is equal to the product of its wavelength and frequency. Therefore, if the speed of light changes but its frequency remains constant, its wavelength must change. This phenomenon is known as the wavelength of light.

Conclusion:
When light undergoes refraction, its frequency remains the same. The change in direction of light is caused by the change in speed, not the change in frequency.

Answer

C

Answer

Frequency is characteristics property of source. while refraction there is no effect on source hence it's frequency did not get effected.

Answer

Wavelength changes right then why frequency remains same ???
