Read moreWhat is frequency and how does it affect waves?
The number of waves that pass a fixed point in a given amount of time is wave frequency. Wave frequency can be measured by counting the number of crests (high points) of waves that pass the fixed point in 1 second or some other time period. The higher the number is, the greater the frequency of the waves.
Read moreWhat does frequency represent in waves?
In physics, the term frequency refers to the number of waves that pass a fixed point in unit time . It also describes the number of cycles or vibrations undergone during one unit of time by a body in periodic motion.
Read moreWhat happens when the frequency is high?
The number of complete wavelengths in a given unit of time is called frequency (f). As a wavelength increases in size, its frequency and energy (E) decrease. From these equations you may realize that as the frequency increases, the wavelength gets shorter . As the frequency decreases, the wavelength gets longer.
Read moreWhat causes higher frequency in waves?
The shorter the wavelength , the higher the frequency, and the higher the pitch, of the sound. In other words, short waves sound high; long waves sound low.
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 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.
