Radio Wave Wavelength Calculation

What is the wavelength of a 92.9 MHz radio wave?

A. 3.2 m

B. 3200 km

C. 3200 m

D. 3.2 mm

Answer:

The wavelength of a 92.9 MHz radio wave is 3.23 m.

Radio waves are a type of electromagnetic radiation with wavelengths in the electromagnetic spectrum longer than infrared light. The wavelength of a radio wave can be calculated using the formula:

wavelength = speed of light / frequency

In this case, we have a frequency of 92.9 MHz, which is equal to 92.9 × 10^6 Hz. The speed of light is approximately 3 × 10^8 m/s. By substituting these values into the formula, we get:

wavelength = (3 × 10^8 m/s) / (92.9 × 10^6 Hz) = 3.23 m

Therefore, the wavelength of a 92.9 MHz radio wave is 3.23 meters. This calculation helps in understanding the relationship between frequency and wavelength of radio waves.
