The longest wavelength in the visible light spectrum is at the red end (at about 750nm) the lowest is violet (450nm). For a given intensity source the energy that can be generated is equal.
The answer you are looking for is 720-680nm
The red end of the spectrum. Red has lower frequency, lower energy and longer wavelength than the blue end of the spectrum.
The color red is the longest wavelength in the visible light spectrum because the less energy a wave carries the longer the wavelength and red carries the least energy of all the colors in the visible spectrum
Violet (purple) is the highest energy color in the visible spectrum. It has a wavelength of about 400nm (4x10-8m), the lowest of all visible light.
The last color you can see at the red end has the lowest frequency,longest wavelength, least energy per photon.The last color you can see at the violet end has the highest frequency,shortest wavelength, most energy per photon.
The shorter the wavelength of visible light, the higher the frequency and the greater the energy of the photons.
Red
The three colors with the longest wavelength are red, orange, and yellow. They have the lowest frequency and highest energy among the visible spectrum of colors.
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).
The red end of the spectrum. Red has lower frequency, lower energy and longer wavelength than the blue end of the spectrum.
The order of the energy spectrum from shortest to longest wavelength is gamma rays, X-rays, ultraviolet light, visible light, infrared light, microwaves, and radio waves.
The color red is the longest wavelength in the visible light spectrum because the less energy a wave carries the longer the wavelength and red carries the least energy of all the colors in the visible spectrum
Violet (purple) is the highest energy color in the visible spectrum. It has a wavelength of about 400nm (4x10-8m), the lowest of all visible light.
The second longest wavelength in the absorption spectrum of hydrogen corresponds to the transition from the n=2 to n=4 energy levels. This transition produces a spectral line known as the H-alpha line, which falls in the red part of the visible spectrum at a wavelength of 656.3 nm.
Red light has the longest wavelength among the visible spectrum because it has the lowest frequency and energy. The longer wavelength of red light causes it to scatter less than other colors, giving it the ability to travel farther through the atmosphere and water.
The last color you can see at the red end has the lowest frequency,longest wavelength, least energy per photon.The last color you can see at the violet end has the highest frequency,shortest wavelength, most energy per photon.
radio wave is form of electromagnetic energy which has the longest wavelength in electromagnetic spectrum
Your question is meaningless. Light is electromagnetic radiation and the colour of light depends on the wavelength of this radiation. There is no such thing as a "weak" wavelength.
