Final answer:

The frequency of the radio waves from the Voyager spacecraft with a wavelength of 0.120 m and speed of 3.00 \(\times 10^8 m/s is 2.50 \(\times 10^8 Hz.

Step-by-step explanation:

The frequency of radio waves transmitted by the Voyager spacecraft through space can be calculated using the formula for wave speed v = f \(\lambda, where v is the wave speed, f is the frequency, and \(\lambda is the wavelength. Given that the wave speed v is 3.00 \(\times 10^8 m/s (the speed of light) and the wavelength \(\lambda is 0.120 m, you can rearrange the formula to solve for frequency: f = v / \(\lambda. Therefore, the frequency f is calculated as 2.50 \(\times 10^8 Hz.

To find the frequency, divide the speed of light (3.00 \(\times 10^8 m/s) by the wavelength given (0.120 m), resulting in a frequency of 2.50 \(\times 10^8 Hz, which is option a).

To find the frequency of the radio waves transmitted by the Voyager spacecraft, we can use the equation:

speed of light = wavelength * frequency

Given that the speed of light is 3.00 * 10^8 m/s and the wavelength is 0.120 m, we can rearrange the equation to solve for frequency:

frequency = speed of light / wavelength

Plugging in the values, we get:

frequency = (3.00 * 10^8 m/s) / (0.120 m) = 2.50 * 10^8 Hz

Therefore, the frequency of the radio waves transmitted by the Voyager spacecraft is 2.50 * 10^8 Hz.
