When light enters a denser medium what happens to the speed of light and its frequency?
first of : denser matter does not relate to the massive matter(nothing like g/cm³ ! ) it rather relates to the optical density of a matter, which is a measure of how much light is absorbed per length. both also do not make any statement about the speed of light in that matter.
what you are looking for is the refractive index n which is the relationship of speed of light in free space(c0) to the speed of light in a matter(v)
n = c0 / v alternative definition n = radical ( mu * epsilon)
where mu and epsilon are properties of the matter that describe if it amplifies magnetic or electircal fields.
n can never be smaller than one , otherwise the speed of light in that matter would be lager than that of the free space, which by Einstein can not be.
in any matter the speed of light is lower than that in free space.
specifically
v= c0/ n
v= c0/ radical ( mu * epsilon)
Conclusion: Depending on the electrical properties of your matter the speed of light varies. It will always be equal or less than the speed of light in free space.
last note: for example with glass the speed of light does not only change according to the matter used, but also the wavelength. This is the reason why prisms can spread a white beam of light out to make a rainbow spectrum.
What else can I help you with?
When light enters from denser medium to rare medium what happens to its phase change?
When light enters from a denser medium to a rarer medium, the phase change it experiences is a shift towards a longer wavelength, known as refraction. This shift in phase is due to the change in the speed of light as it travels through the different mediums.
What happens to the intensity of light when it enters a dnser medium?
There's no reason to expect that the intensity of light must necessarily change when it enters a different medium.
What happens to the speed of light as light travels though materials?
The speed of light is not affected by the density of the medium. Its the path of the light that is affected . Phenomenon like reflection or refraction take place when the light goes to different medium
Why frequency of light never change when light changes medium?
When light enters another medium it changes speed, but thewavelength changes correspondingly so that the frequency does not change. For example, if light enters a medium where its speed is cut in half, then the wavelength will also be reduced by half.
When a ray of light from air enters to glass what happens to wavelength?
It will not change. Glass slows light but does not change it frequency.
What happens to wavelength as a wave leaves the air and enters the perspex?
The wavelength bends forward as it leaves the air and enters the Perspex. The frequency of the wavelength will also increase.
What happens when a wave moves through a denser medium?
When a wave moves through a denser medium, its speed decreases while its frequency remains constant. The wave will also experience refraction, causing it to change direction as it enters the denser medium. Additionally, the wavelength of the wave will shorten as it moves into the denser medium.
What happens when light enters a denser medium and is refracted as far as wave speed and frequency?
When light enters a denser medium, its speed decreases, causing it to bend or refract toward the normal of the boundary between the two mediums. The frequency of the light remains constant as it passes through the boundary, but its wavelength changes.
What happens to a sound wave when it enters a denser medium?
When a sound wave enters a denser medium, its speed decreases and its wavelength also decreases while the frequency remains the same. This causes the sound wave to bend towards the normal line at the boundary between the two media.
When a wave travels from a denser medium to a less dense medium what happens to its frequency?
The frequency of the wave remains the same when it travels from a denser to a less dense medium. However, the wave will change its speed and wavelength.
What takes place as a light wave enters a denser medium?
When a light wave enters a denser medium, it slows down and changes direction. This is due to the change in the speed of light in different mediums, which causes the wave to refract or bend. The frequency of the light wave remains constant, but its wavelength can change.
When light enters from denser medium to rare medium what happens to its phase change?
When light enters from a denser medium to a rarer medium, the phase change it experiences is a shift towards a longer wavelength, known as refraction. This shift in phase is due to the change in the speed of light as it travels through the different mediums.
When the light enters a denser medium what happens to the wavelengths?
The denser an object is, the slower a wave will travel through it because the wave will interact (collide!) with more molecules. Each collision will serve to slow down the wave of light. Therefore, the wavelength will increase, becoming longer.
Why light bends away from normal when enter from denser to rare medium?
Light slows down when it enters a denser medium due to increased interactions with the molecules in the medium. This slowing causes the light waves to bend away from the normal line to maintain the same frequency and to obey the law of conservation of energy.
Why does wavelength o light decrease when enter to denser medium?
When light enters a denser medium, its speed decreases due to interactions with the medium's particles. This change in speed causes the frequency of the light to remain constant but the wavelength to decrease, following the equation v = fλ, where v is the speed of light, f is the frequency, and λ is the wavelength.
Why frequency of light is not change When it enter from a rarer medium to denser medium?
Frequency is a function of the energy level of the photon. Changing the medium does not change that energy level.
What is effect on wavelength of light when it enter dense medium?
When light enters a denser medium than it was previously travelling in, the wavelength gets shorter because the speed of the light slows down: v=w/f where v is the velocity of a wave, w is the wave length, and f is the frequency. When light enters the new medium, f does not change but v decreases so w also decreases. Actually, the density of the medium is not accurate. The medium is not denser it just is "optically denser" which means it has a higher index of refraction. It has nothing to do with actual density, which is weight divided by volume.
