When discussing waves, frequency and wavelength are two essential concepts that are interconnected. Frequency refers to the number of waves that pass through a point in a second, while wavelength is the distance between two corresponding points in a wave. As such, changes in one of these properties can significantly affect the other. In this blog post, we will focus on what happens to the frequency of a wave when its wavelength increases.

Firstly, it is important to note that frequency and wavelength are inversely proportional to each other. This means that as the wavelength of a wave increases, its frequency decreases and vice versa. This relationship is known as the wave speed equation, which states that the product of frequency and wavelength equals the speed of the wave. Mathematically, this can be expressed as:

Speed = Frequency x Wavelength

This equation implies that if the speed of the wave remains constant, any increase in its wavelength must be accompanied by a decrease in its frequency. For example, if we consider a sound wave with a frequency of 440 Hz (which corresponds to the musical note A) and a wavelength of 0.77 meters, its speed would be approximately 340 meters per second (the speed of sound in air). If we were to increase the wavelength of this wave to 0.88 meters, its frequency would decrease to 396 Hz (which corresponds to the musical note G).

The reason behind this inverse relationship between frequency and wavelength lies in the nature of waves themselves. Waves are characterized by their oscillatory motion, which means that they move up and down (or back and forth) around a central point. The frequency of a wave determines how quickly it oscillates, while its wavelength determines the distance between two points of maximum or minimum displacement. Therefore, if the wavelength of a wave increases, the distance between two points of maximum or minimum displacement also increases. This results in a slower oscillation, which leads to a decrease in frequency.

In conclusion, when the wavelength of a wave increases, its frequency decreases due to the inverse relationship between these two properties. This relationship is governed by the wave speed equation, which states that the product of frequency and wavelength equals the speed of the wave. Understanding this relationship is crucial in many fields, including physics, engineering, and telecommunications.
