Yes. The visible spectrum of light is much shorter than the shortest radar (radio) wave.
Too Long.
Radar waves are too long to be seen by the human eye. They have wavelengths ranging from a few millimeters to several meters, which are beyond the visible light spectrum. However, radar technology allows us to detect and visualize these waves for various applications like weather forecasting and aircraft navigation.
no they are too long
Radar comes from Radio Detection and Range. By definition, it uses radio waves. Ultra sonic waves, very high frequency audio waves, are used in Sonar, the name being analogous to Radar. Infra Sonic waves are of far too long a wavelength to be useful for any measurement of the distance of the target. [And there are some technical reasons as well - not dealt with here.]
They are too long. For a good comparison of different waves, look up "electromagnetic spectrum".
No, the visible light spectrum falls between infrared and ultraviolet light on the electromagnetic spectrum. Radar waves have longer wavelengths than visible light, while X-rays have shorter wavelengths.
Television waves are radar waves or radio waves simply because they are useful for long term communication and are readily reflected by the ionosphere. Microwaves are used for short term communication very rarely and for heating purposes. All three however travel at the same speed that is 299,792,468 m/s.
RADAR determines the distance and direction to anything that reflectsradio waves ... usually material objects, but it responds to atmosphericphenomena too.
Yes. What you need to look at is the electromagnetic spectrum. There are many great graphical illustrations of this on the web.
no because the wavelength of the waves are too short for us to see
I looked it up in my physics text book and it says that the wavelength is too long to be seen by the human eye.
Having a radar means you can detect enemies before they can see you (unless they have a radar too).
