What is the wavelength corresponding to a frequency of 2 MHz?

To determine the wavelength corresponding to a frequency, you can use the formula:

[ \text{Wavelength (meters)} = \frac{300}{\text{Frequency (MHz)}} ]

For a frequency of 2 MHz, applying the formula gives:

[ \text{Wavelength} = \frac{300}{2} = 150 \text{ meters} ]

This implies the correct wavelength is 150 meters, which corresponds to a frequency of 2 MHz.

The calculation is based on the speed of light in a vacuum, approximately 300,000 kilometers per second (or 300 meters per microsecond), and the relationship between frequency and wavelength in electromagnetic waves. At lower frequencies, such as 2 MHz, the wavelengths are longer than at higher frequencies, and this relationship is critical in understanding radio wave propagation and antenna design. The answer of 150 meters reflects an accurate application of the fundamental physics of electromagnetic waves.
