If something has a longer MHz, does it have a longer wavelength

No, having a longer MHz (megahertz) does not necessarily mean that something has a longer wavelength. The relationship between frequency and wavelength is defined by the wave equation:

Speed of light (c) = Frequency (f) * Wavelength (λ)

According to this equation, wavelength is inversely proportional to frequency. That means, as frequency increases, wavelength decreases, and vice versa.

MHz is a unit of frequency, representing one million cycles per second. It is often used to measure the frequency of electromagnetic waves, such as radio waves. Higher MHz values indicate higher frequencies, which correspond to shorter wavelengths.

So, if something has a longer MHz, it means it has a higher frequency and a shorter wavelength, not a longer wavelength.
