As frequency increases, what happens to the wavelength?

• A. It becomes longer
• B. It remains the same
• C. It becomes shorter
• D. It becomes erratic

Answer: (C)

As frequency increases, the wavelength of a wave becomes shorter. This relationship is described by the wave equation, which states that the speed of a wave is equal to its frequency multiplied by its wavelength. In a constant medium, the speed of the wave remains constant. Therefore, when the frequency increases, the wavelength must decrease to keep the equation balanced. This is why option C is the correct choice. Understanding this concept is fundamental in fields like avionics, where the behavior of electromagnetic waves is crucial for communication systems, radar, and navigation devices. In practical terms, higher frequencies allow for greater resolution and more detailed information transmission, which is vital in aircraft systems for tasks such as radar detection and data communications. The other options illustrate different scenarios that do not accurately describe the relationship between frequency and wavelength in the physics of waves.
