Radar has the longer wavelength.
Visible Light
Passive remote sensing picks up wave lengths of the light spectrum occurring on their own such light in photography. Active remote sensing will send out a wavelength of the spectrum and measure how it bounces back like radar.
The wavelength gets longer.
The color red has the longest wavelength of any color.
A fluorescent lamp or fluorescent tube is a gas-discharge lamp that uses electricity to excite mercury vapor. The excited mercury atoms produce short-wave ultraviolet light that then causes a phosphor to fluoresce, producing visible light. I also put in the URL where I found the answer in case you would like to find out more about fluorescent lights.http://en.wikipedia.org/wiki/Fluorescent_lights
No. Radar use electromagnetic radiation of a much longer wavelength
for wavelength, the longer of the two is visible light, but the longest type of rays are radio waves (some of them have a wavelength as long as a football field)
Radio waves have a longer wavelength than visible 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.
Infra-red radiation has a wavelength adjacent to but longer than visible light.
Heat has longer wavelength / lower frequency than visible light.
Red light (longer wavelength)
Radio, microwaves, radar, and infrared radiation have.
Infrared has a smaller wavelength than microwaves.
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.
infrared
Infrared has a longer wavelength, and a lower frequency, than visible light.
