Red light has the longest wavelength that's visible to the eye.
Violet light, just past blue in the rainbow, has the shortest wavelength
that's visible to the eye. It's roughly half the size of a wave of red light.
Red light has a longer wavelength - and a lower frequency - than violet light. Red light also has less energy.
The wavelength of red light is roughly double the wavelength of violet light.
Green light has longer wavelength.
Red
green
Yes, red has a lower frequency than green. It therefore has a longer wavelength.
Orange has a longer wavelength than yellow. On the spectrum of visible light red is longest and violet is shortest.
The colour of visible light with the longest wavelength is red (approximately 700 nanometres).
Red.
Green has the shortest wavelength of those.
Yes, red has a lower frequency than green. It therefore has a longer wavelength.
Orange has a longer wavelength than yellow. On the spectrum of visible light red is longest and violet is shortest.
The colour of visible light with the longest wavelength is red (approximately 700 nanometres).
The bright green light has a higher frequency (shorter wavelength) and a smaller amplitude than the dim red light.
Shorter or longer than what ? The wavelength of visible light is shorter than that of radio and heat, and longer than the wavelength of X-ray and gamma radiation. And the wavelength of green light is shorter than red light but longer than blue light.
Red.
Green has the shortest wavelength of those.
Sound waves are much longer then light waves.
red
Blue light has shorter wavelength than red light. Remember ROYGBIV? If you reverse the sequence - VIBGYOR, you have all the colors listed from shortest wavelength to longest wavelength in the visible spectrum. Or, you can just simply consult an electromagnetic (EM) spectrum.
Red light (longer wavelength)
The difference is the wavelength's of the two colors, Red is on the "right" end of the visible light spectrum and thus "bigger" wavelength about 640-700 nanometers while Green is more on the "left" side at around 500 nanometers.
