Different frequencies of light are different colors.
The Doppler effect is a phenomenon observed whenever the source of waves is moving with respect to an observer. The Doppler effect can be described as the effect produced by a moving source of waves in which there is an apparent upward shift in frequency for the observer and the source are approaching and an apparent downward shift in frequency when the observer and the source is receding. The Doppler effect can be observed to occur with all types of waves - most notably water waves, sound waves, and light waves.
google it lazy bum. No, light waves are just that-- waves. The color of the wave is determined by it's frequency- normal light is white because it is low frequency. The frequency is how fast the light "waves". But a laser pointer has red light, which has a higher frequency, and therefore is only one color. Hope this helps!
Red light waves are almost double the length of blue or violet light waves. Wavelength is inversely proportional to frequency; red light has a higher frequency than blue light.
Its wavelength (or frequency).
Waves can be varied (modulated) by either changing amplitude (amplitude modulation AM) or changing frequency (wavelength) (frequency modulation FM). The modulations are used to carry the information signal.
Radar waves have a lower frequency that light waves.The frequency of a light wave is related to wavelength and speed by the equation c = »½. The color of a light wave is also determined by the frequency. The amplitude and brightness are not related to the frequency.
by changing the amplitude or frequency of the radio waves.

Red waves have the lowest frequency of all light waves; there is no wave with a lower frequency.
they are a high frequency
They have both.
