# Does red or violet have a longer wavelength?

## Does red or violet have a longer wavelength?

On one end of the spectrum is red light, with the longest wavelength. Blue or violet light has the shortest wavelength.

What is the length of purple waves when compared with length of red waves?

As the full spectrum of visible light travels through a prism, the wavelengths separate into the colors of the rainbow because each color is a different wavelength. Violet has the shortest wavelength, at around 380 nanometers, and red has the longest wavelength, at around 700 nanometers.

What happens to the wavelength of colors of light from violet to red?

The separation of visible light into its different colors is known as dispersion. The red wavelengths of light are the longer wavelengths and the violet wavelengths of light are the shorter wavelengths. Between red and violet, there is a continuous range or spectrum of wavelengths.

### What type of wave has the longest wavelength?

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

Why is red the longest wavelength?

We know that Frequency is inversely proportional to wavelength, so Red light rays have the lowest frequency and highest wavelength value. This means that Red light rays have the least number of waves in a second than any other radiation. Hence option A is the correct option.

What is the shorter wavelength?

Waves of blue light have a shorter wavelength than waves of red light. 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.

#### What does the longer wavelength indicate?

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

Does Purple have a wavelength?

Scientifically, purple is not a color because there is no beam of pure light that looks purple. There is no light wavelength that corresponds to purple.

What is the wavelength of radio waves?

Radio wave, wave from the portion of the electromagnetic spectrum at lower frequencies than microwaves. The wavelengths of radio waves range from thousands of metres to 30 cm. These correspond to frequencies as low as 3 Hz and as high as 1 gigahertz (109 Hz).

## How is wavelength related to the energy of the colors of light?

The visible light portion of the electromagnetic spectrum shows the rainbow of colors, with violet and blue having shorter wavelengths, and therefore higher energy. At the other end of the spectrum toward red, the wavelengths are longer and have lower energy (Figure 3).

How is wavelength related to frequency?

Frequency and wavelength are inversely proportional to each other. The wave with the greatest frequency has the shortest wavelength. Twice the frequency means one-half the wavelength. For this reason, the wavelength ratio is the inverse of the frequency ratio.
