Speed of red light and blue light in a vacuum?

In a vacuum the speed of red and blue light are the same as all light, 300,000,000m/s. Their frequency and wavelength will be different but the speed remains the same.


What has a longer wavelength red or green?

Red light has the longest wavelength that's visible to the eye.Violet light, just past blue in the rainbow, has the shortest wavelengththat's visible to the eye. It's roughly half the size of a wave of red light.


Which type of visible light has the longest wavelength?

The longest wavelength / lowest frequency visible light is the red end of the spectrum. The shortest wavelength / highest frequency visible light is the violet end of the spectrum.


Is a red light a visible light with the shortest wavelength?

No, red light has the longest wavelength within the visible light spectrum.


Is the Visible light with the shortest wavelength a red light?

No, red light has the longest wavelength within the visible light spectrum.


What is the relationship between the speed of light and wavelength?

The speed of light is constant in a vacuum, and it is directly proportional to the wavelength of light. This means that as the wavelength of light increases, the speed of light remains the same.


Which of the colors of light has the longest wavelength?

The color red has the longest wavelength of any color.


What is a sentence for wavelength?

The wavelength of a transverse wave is the distance between adjacent crests or troughs (peaks or valleys).


True or false visibe light with the shortest wavelength is red light?

No, red is the longest wavelength of visible light, with the lowest frequency and the least energy. Violet light has the shortest wavelenght, with the highest frequency and the most energy (of visible light).


Which color of light has the highest wavelength?

Red light has the longest wavelength among the visible colors.


What color of the rainbow has the longest wavelength?
