# Why does red have a longer wavelength than blue?

## Why does red have a longer wavelength than blue?

Blue light has shorter waves, with wavelengths between about 450 and 495 nanometers. Red light has longer waves, with wavelengths around 620 to 750 nm. Blue light has a higher frequency and carries more energy than red light.

Does red have the longer wavelength?

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.

Why does red light have a lower frequency than green light?

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

### What is the longest wavelength?

Radio waves have the longest wavelength, and gamma rays have the shortest wavelength.

Why longer wavelengths travel further?

HallsofIvy said: You are going to have to be a lot more precise! Sound waves?? or Electro-magnetic (light and radio) waves. In the atmosphere or open space (sound waves, of course, cannot exist without a medium- electromagnetic waves travel through open space any distance without regard to their frequency).

Which has the longest wavelength?

## What does a longer wavelength mean?

lower frequency
Conclusion: a longer wavelength means a lower frequency, and a shorter wavelength means a higher frequency!

Why are shorter wavelengths faster?

So, if the wavelength of a light wave is shorter, that means that the frequency will be higher because one cycle can pass in a shorter amount of time. That means that longer wavelengths have a lower frequency. Conclusion: a longer wavelength means a lower frequency, and a shorter wavelength means a higher frequency!

What is a longer wavelength?

The wavelength of a wave describes how long the wave is. The frequency of a wave is inversely proportional to its wavelength. That means that waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength. Light waves have very, very short wavelengths.

### Why do shorter wavelengths have higher energy?

The energy associated with a wave is directly proportional to its frequency. Hence, the higher the frequency, the shorter the wavelength and the higher the energy of the wave. Red light, then, has a lower frequency and is associated with less energy than blue light.

Why do longer wavelengths travel faster?

If one set has a longer wavelength, it will have a lower frequency (more time between waves). If the other set has a shorter wavelength, it will have a higher frequency (less time between waves). Wavelength and frequency go opposite of each other. Light moves even faster AND has shorter wavelengths.

What is the wavelength of red light in visible light?

Red light has the lowest frequency of the visible light spectrum, and thus has a longer wavelength. The shortest wavelength of visible light is actually violet, which has a much higher frequency, and why much of the most powerful lasers are violet. You can deduce this also from this little tip: Infra red means below red.

## What happens when red light vibrates at the lowest frequency?

Red vibrates at the lowest frequency of visible light. When this happens at the lowest frequency of visible light, it produces red light. Lower frequency means it happens less often over a period of time. Each single wave is stretched out over a longer time period thus a longer wave length. Click to see full answer.

What is the difference between red light and blue light?

Red light has a slightly longer wavelength than blue light. Red light (at one end of the visible spectrum) has a longer wavelength than blue light. However, another way of distinguishing between the different colors of light is by their frequency, that is, the number of waves that pass by a point every second.

Which color of light has the highest frequency and energy?

Violet light has the shortest wavelength, which means it has the highest frequency and energy. Red has the longest wavelength, the shortest frequency, and the lowest energy. There is no wavelength assigned to indigo.
