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).
What is the longest wavelength in nm that can dissociate a molecule of HI?
406 nm
What is the second longest wavelength in the absorption spectrum of hydrogen?
97.26 nm
Which color will have the longest wavelength which corresponds to the lowest energy?
Red
Which colour has the shortest wavelength?
Shortest wavelength means the highest frequency, meaning the photons have the highest energy. That is color violet. The violet light colors the skin brown. Red light with lower energy photons cannot do that.
What is the longest wavelength photon?
There is no longest wavelength for photons. It can be arbitrarily long.
Which electromagnetic waves has the longest wavelength?
"radio waves" have longest wavelength..
Which light has the longest wavelength and the shortest frequency?
The longest visible wavelength of light appears red. "Longest wavelength" is equivalent to 'lowest frequency'.
Which colour have longest wavelength in the visible spectrum?
Red light has the longest wavelength.
What color of visible light has longest wavelength?
Red is the longest wavelength of visible light
What color of visible light has the longest wavelength?
Red is the longest wavelength of visible light
Photons with lowest energy have the?
-- longest wavelength -- lowest frequency
What is the longest wavelength on a electromagnetic spectrum?
The electromagnetic waves with the longest wavelength are called radio waves.
Which of the colors of light has the longest wavelength?
The color red has the longest wavelength of any color.
Longest wavelength in the spectrum of color?
The color red has the longest wavelength of all the colors in the light spectrum.
Which color light has a longer wavelength?
The colour of visible light with the longest wavelength is red (approximately 700 nanometres).
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.
