The wavelength of the sound wave becomes longer as the car moves away. A longer wavelength means that not as many wave cycles can pass in a given time interval, so the frequency is lower, and thus the pitch of the sound is much lower .
Read moreWhat is the example of wave with a long wavelength?
Infrared radiation has wavelengths between 700 nm and 1 millimeter (mm). In infrared the detected radiation is turned into an image on a screen, hotter objects showing up brighter. Radio waves have the longest wavelengths in the electromagnetic spectrum.
Read moreWhat has a long wavelength and low frequency?
The frequency of a wave is inversely proportional to its wavelength. That means that waves with a high frequency have a short wavelength, while waves with a low frequency have a longer wavelength. Light waves have very, very short wavelengths.
Read moreWhat type of wave has the longest wavelength and the lowest frequency?
Radio Waves — The waves in the electromagnetic spectrum that have the longest wavelengths and lowest frequency are called radio waves. Radio waves are used to transmit information from the antenna of a broadcasting station to the antenna of your radio or TV.
Read moreWhat wavelength do green things absorb?
The transmitted light is the light we see, and it looks orange. Colored objects look the way they do because of reflected light. When sunlight is shined on a green leaf, the violet, red and orange wavelengths are absorbed.
Read moreDoes green have a high wavelength?
The distance from the “crest” (top) of one wave to the crest of the next wave is the wavelength. Alternately, we can measure from the “trough” (bottom) of one wave to the trough of the next wave and get the same value for the wavelength. The frequency of a wave is inversely proportional to its wavelength.
Read moreWhat does spectrum mean in color?
The spectrum is the range of different colours which is produced when light passes through a glass prism or through a drop of water . A rainbow shows the colours in the spectrum.
