The relationship between frequency and wavelength of a wave is described by option C: higher frequency corresponds to a shorter wavelength.
To understand this relationship, it's important to first define frequency and wavelength. Frequency refers to the number of complete cycles of a wave that occur in one second, measured in hertz (Hz). Wavelength, on the other hand, is the distance between two corresponding points on a wave, such as the distance between two adjacent crests or troughs.
Now, consider a wave traveling through a medium. When the frequency of the wave increases, it means that more complete cycles are occurring in one second. As a result, the wave becomes more compressed, and the distance between two adjacent points on the wave decreases. This decrease in distance is known as a shorter wavelength.
Conversely, when the frequency of a wave decreases, fewer complete cycles occur in one second. This leads to a less compressed wave, and the distance between two adjacent points on the wave increases. This increase in distance is known as a longer wavelength.
In summary, frequency and wavelength are inversely proportional. As the frequency increases, the wavelength becomes shorter, and as the frequency decreases, the wavelength becomes longer.
