Does violet light or red light travel 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).
Which Colour of light travels fastest in air?
The wavelength of visible light increases from violet to red colour. It is highest for red colour. Hence, red colour travels fastest in any medium except air.
How fast does green light travel?
Speed of Light Light travels at almost 300,000,000 meters per second (to be exact: 299,792,458 meters per second) in a vacuum.
What color light moves the fastest?
red color
So according to equation (1) velocity of light is directly proportional to the wavelength. So violet color has minimum velocity of light and red color has maximum velocity of light when it passes through the glass. Hence the red color of white light travels fastest in the glass.
What are the speed of red and violet Colour in air?
Speed of red light is faster than violet because wavelength of red is greater than violet. In free space both move with same speed but in a medium red light moves faster than violet light.
Does red light travel faster than green light?
Hint: We know that according to the formula of wavelength in relation with velocity and frequency, that wavelength and velocity both are directly proportional to each other so velocity of light will be maximum for the light which has the highest wavelength. Velocity of light is directly proportional to its wavelength.
Which color travels faster through red or blue?
In vaccum all light travels at the same speed. In most materials the blue and violet light travels faster than red. This phenomenon is called dispersion and it is explained on Wikipedia.
Which colour of light travels fastest in a prism?
red light
During dispersion through prism, red light travels fastest and violet travels slowest of all the seven colours.
Which color of light has the longest wavelength green or violet?
The visible colors from shortest to longest wavelength are: violet, blue, green, yellow, orange, and red. Ultraviolet radiation has a shorter wavelength than the visible violet light. Infrared radiation has a longer wavelength than visible red light. The white light is a mixture of the colors of the visible spectrum.
Which colour of light travels faster in any medium except air?
As the refractive index of red color is less as described above, the velocity of red light will be more in any medium except air.
Does blue light travel faster than green light?
Blue light moves faster than green light C. All the colors of the white light move with the same speed D. Yellow light moves with the mean speed as that of the red and the violet light. All the colors of white light move with the same speed because speed of light doesn’t depend on color and has a constant value.
Which color of light travels faster through glass?
Violet light has the shortest wavelength and is bent the most. Thus violet light travels more slowly through glass than does any other color and red light travels fastest. Like all other wave phenomena, the speed of light depends on the medium through which it travels.
Why does red light travel faster than violet light?
In vaccum all light travels at the same speed. In most materials the blue and violet light travels faster than red. This phenomenon is called dispersion and it is explained on Wikipedia. There are some materials which have so called anomalous dispersion, which means red would be faster than violet but I don’t know what they are.
Which material has the fastest and slowest velocity of light?
Repeat with different materials and compare the results. Light will have the fastest velocity when it travels through the air. Light will have the slowest velocity when it travels through gelatin. Why? Light slows down when passing through different transparent materials.
Which has the fastest velocity when it travels through air?
Light will have the fastest velocity when it travels through the air. Light will have the slowest velocity when it travels through gelatin.
