The wavelength is the length of the wave from one peak to the next.

Wavelength

The peak refers to either a wave's crest or trough (highest or lowest point, respectively).

Peak

Frequency is defined as the number of waves that pass a specific point in a given period of time. There is an inverse relationship between a wave's frequency and its wavelength; longer wavelengths correspond to lower frequencies, while shorter wavelengths are associated with higher frequencies.

Frequency of a Wave

A fundamental property of waves is the inverse relationship between their wavelength and frequency. This means that as a wave's length increases, its frequency decreases, resulting in longer waves having lower frequencies and shorter waves having proportionally higher frequencies.

Inverse Relationship Between Wavelength and Frequency

Imagine four different waves are measured. Which of the following descriptions represents the wave with the longest wavelength?

Consider two distinct waves, Wave A and Wave B. For Wave A, the measured distance from the highest point of one wave to the highest point of the very next wave is 10 nanometers. For Wave B, the same measurement is 20 nanometers. Based on an analysis of this information, what can you conclude?
