Answer:

The formula relating wavelength, frequency, and speed is:

speed = wavelength x frequency

Rearranging this equation to solve for frequency, we get:

frequency = speed / wavelength

Plugging in the given values, we get:

frequency = 300,000,000 m/s / 2 m

frequency = 150,000,000 Hz

Therefore, the frequency of the wave is 150,000,000 Hz.
