What color of light has the highest frequency?
Violet waves
What is the depression of light?
Dispersion of light is caused by the change of speed of light ray (resulting in angle of deviation) of each wavelength by a different amount. Note: White light comprises of seven visible colours (VIBGYOR) whereas black (or dark) signifies the absence of light rays.
Why is red light faster than violet light?
Red light is faster than violet light because red light have longer wavelength while violet light have shorter wavelength. But this is applicable in all mediums except Vaccum. Answer: In other words, in vacuum blue and red colored light travel at the same speed c.
Is red light or violet light faster?
Violet travels the slowest so it is on the bottom and red travels the fastest so is on the top. This is because what is called the index of refraction, (the ratio of the speed of light in a vacuum to the speed of light in a material), is increased for the slower moving waves (i.e. violet).
Does green light travel faster than red light?
So red light vibrates at about 400 million million cycles per second. Fast! Higher frequency (with shorter wavelength) has more energy: Red light has lower frequency, longer wavelength and less energy….Visible Spectrum.
| Color | Wavelength Range (nm) |
|---|---|
| Green | 495–570 |
| Blue | 450–495 |
| Violet | 380–450 |
Is Green faster than blue?
In this case, the shorter wavelengths are refracted more (they are slowed down more) than the longer wavelength colors. So, in this case, the blues travel faster than the greens and reds. In the case of Flint glass, the blue wavelengths travel slower than the longer greens, yellows, and red wavelengths.
Does blue light or red light travel faster?
Because the number of subquantum energy in a red photon is less than that of a blue photon, red photon interactions are less than the blue photon in the medium. So, the red light travels faster than the blue light.
What is the difference between white light and blue or red light?
On one end of the spectrum is red light, with the longest wavelength. Blue or violet light has the shortest wavelength. White light is a combination of all colors in the color spectrum. For example, a red wagon looks red because it reflects red light and absorbs blue and green light.
Do all colors of white light travel at the same speed?
In empty space, all colors travel at the same speed called c. Light of different wavelengths, or colours, travels at different speeds when they travel through any medium other than vacuum.
Does light change speed?
Yes. Light is slowed down in transparent media such as air, water and glass. The ratio by which it is slowed is called the refractive index of the medium and is always greater than one. When people talk about “the speed of light” in a general context, they usually mean the speed of light in a vacuum.
What is the slowest speed of light?
38 mph
