What happens when light passes into a material where the speed of light is faster?
-- Its speed increases. -- Its wavelength increases. -- It refracts away from the normal to the interface at the point of incidence.
What happens to signal's wavelength as its frequency increases?
Using the relationship C = n lambda C - velocity of light, n-frequency of radiation and lambda- the wavelength. So as frequency increases definitely its wavelength decreases.
How does the wavelength of gamma rays compare to the wavelength of visible light?
It is electromagnetic radiation, which is the same in composition as visible light but has a much higher frequency/shorter wavelength, and will do damage to any biological material it passes through. Both travel at the same speed ('velocity of light') but gamma radiation can penetrate material opaque to visible light.
How many times greater is the speed of infrared light than the speed of violet light in vacuum wavelength of the violet light is around 400nm and wavelength of infrared is 800nm?
It isn't. The velocity of both is the same at about 2.998x108m/s. A change in wavelength is associated with a change in frequency not velocity. The frequency of Ultraviolet light is about 750 PHz (Peta Hertz) while that of infrared half that at 375PHz.
What is the wavelength of a 900 MHz signal in free space?
Lambda (wavelength) = Velocity / Frequency = 3 x 10E8 m/sec / 900 x 10E6 /sec = 33.3 cm using Velocity = c (the speed of light in a vacuum)
What happens when light passes through a plasma?
Light passes thru, gets absorbed or is reflected dependent on the wavelength of light and the density of the plasma.
What happens to light as it passes through different mediums?
Its speed and wavelength change.
How are sound waves are affected by their frequency and the medium through which the sound wave passes?
The wavelength is equal to the local velocity of sound divided by the frequency, As with light, there can be refraction when sound passes from one medium to another with a different sound velocity.
What happens when light passes into a material where the speed of light is faster?
-- Its speed increases. -- Its wavelength increases. -- It refracts away from the normal to the interface at the point of incidence.
When the light passes through the second medium what happens to the wave that causes the light to bend?
When light passes through a second medium with different refractive index as the first medium, its velocity will decrease or increase depending on its wavelength and the difference in refractive index of the two media. This causes the 'bending' of light as each of its components try to travel through the second medium at different velocities.
What happens to signal's wavelength as its frequency increases?
Using the relationship C = n lambda C - velocity of light, n-frequency of radiation and lambda- the wavelength. So as frequency increases definitely its wavelength decreases.
Is reflection the bending of light?
No,its called refraction. this actually happens when the light passes from one medium to another and thus the velocity of light changes, which enable the light to bend.
Which parameter of light doesnt change on reflection?
Frequency is the parameter of light which doesnt change on reflection because it is the ratio of velocity of light in medium and wavelength of the particle.Hence,when velocity increases wavelength also increases and when velocity decreases wavelength also decreases but its ratio always remains constant.
Is reflection the bending of light rays?
No,its called refraction. this actually happens when the light passes from one medium to another and thus the velocity of light changes, which enable the light to bend.
Is the bending of light rays a reflection?
No,its called refraction. this actually happens when the light passes from one medium to another and thus the velocity of light changes, which enable the light to bend.
What is the frequency of light with a wavelength of 6.14x10-7?
Frequency=velocity of light/wavelength We know that the velocity of light is 3x10^8m/s From your wavelength, I am assuming that the number is in meters Thus the frequency =(3x10^8)/(6.14x10^-7) frequency = 4.8859x10^14 Hz
How does the speed of light depend on the wavelength?
The equation relating the velocity, wavelength and frequency of an electromagnetic wave is given byv=f λwhere v - velocity of the em wavef - frequency of the em wave andλ - wavelength of the em wave------------------------------------------------------------------------------------------------It is so important to know that velocity of light depends on the nature of the medium and does not depend on the wavelength.
