Answer and Explanation: The color red has the longest wavelength. Red has a wavelength range of 620-740 nanometers in the visible spectrum. Red has the longest wavelength because the color takes less energy to carry than other lights in the visible spectrum.
Is red the shortest wavelengths of visible light?
The wavelengths of visible light are: 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. If you want a number, it's around 445 nanometers, but it doesn't appear on most spectra.
What has a longer wavelength blue or red?
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.
Are the longest wavelengths of visible light red?
When the visible light travels through a prism, the visible light gets separated into a spectrum of colour. Red colour has the longest wavelength of 700 nm, and violet has the shortest wavelength of 380 nm. These colours arrange themselves according to the wavelength as the spectrum of rainbow colours.
Why does red light have a long wavelength?
Why does red have the longest wavelength? 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.
Does red the longest wavelength?
We see these variations as colors. 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 have the lowest frequency?
Red has the longest wavelength of visible light, so it has the lowest energy. Violet light has the shortest wavelength, and so it has the highest level of energy of visible light. Radio waves have the longest wavelength and the lowest level of energy.
What color has the highest longest wavelength?
Red has the longest wavelength and violet has the shortest wavelength. When all the waves are seen together, they make white light. Ultraviolet (UV) light—is radiation with a wavelength shorter than that of visible light, but longer than X-rays, in the range 10 nm to 400 .
Why is violet the shortest wavelength?
The smaller the wavelength of the light the more the light is scattered by the particles in the atmosphere. Thus, the light with the higher wavelengths pass through the atmosphere with little or no scattering, while blue and violet waves are more scattered.
Why does red light have a longer wavelength than blue?
1 Expert Answer Look no further! Red light has a wavelength close to 700nm, and blue is close to 400nm. Wavelength is related to frequency by the equation c (speed of light) = wavelength * frequency. So red has lower frequency and lower energy than blue light.
Which color has the longest wavelength from left to right?
RedWe see these waves as the colors of the rainbow. Each color has a different wavelength. Red has the longest wavelength and violet has the shortest wavelength.
Which wavelength is the longest?
The wave type with the longest wavelength is radio waves. Wavelength is the distance between crests on a wave. In the electromagnetic spectrum,...
Does color exist without light?
Color Doesn't Exist Without Light.
Does wavelength affect color?
The wavelength of visible light determines the color that the light appears. Light with the longest wavelength appears red, and light with the shortest wavelength appears violet. In between are the wavelengths of all the other colors of light. A prism separates visible light into its different colors.
What wavelength is red?
around 620 to 750 nmRed light has longer waves, with wavelengths around 620 to 750 nm.
Does red have high frequency?
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.
Which wavelength carries the most energy?
Gamma raysGamma rays have the highest energies and shortest wavelengths on the electromagnetic spectrum.
