# Quick Answer: Which Colour Has A Greater Speed In Glass?

## What color has the highest energy?

violetWhen it comes to visible light, the highest frequency color, which is violet, also has the most energy.

The lowest frequency of visible light, which is red, has the least energy..

## Which Colour has a greater speed in vacuum?

Solution. (a) In vacuum, both have the same speeds. (b) In a glass, red light has greater speed.

## Which light has highest speed?

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).

## Are red cars faster?

It’s a physics phenomenon called redshift. Red light travels faster, so the car can slipstream it. It provides extra testosterone to the driver, when he doesn’t have enough.

## What color is lowest in energy?

RedRed is the lowest energy visible light and violet is the highest.

## Is black the absence of Colour?

Black is the absence of light. … Some consider white to be a color, because white light comprises all hues on the visible light spectrum. And many do consider black to be a color, because you combine other pigments to create it on paper. But in a technical sense, black and white are not colors, they’re shades.

## Which Colour has the least speed in glass?

Violet colourViolet colour has shortest wavelength and hence it travels through glass with the minimum speed.

## Which Colour has maximum speed in water?

red colourThus speed of light in water is maximum for red colour.

## Which light travels faster in vacuum?

Answer. ☆ Light Travel Faster in vaccum because in vaccum, their is no material to obstruct the propagation of light. ☆ The Refractive Index of vaccum is lowest.

## Which Colour is the fastest?

redThe speed of light in glass is not independent of the colour of light it is because the refractive index of violet colour is more than the refractive index of red colour. That is why the velocity of red light fastest.

## Is red faster than blue?

Fast! Higher frequency (with shorter wavelength) has more energy: Red light has lower frequency, longer wavelength and less energy. Blue light has higher frequency, shorter wavelength and more energy.
