At what frequency does the spacecraft radio transmitter operate if its wavelength is 15m?
| August 12, 2021 | education
It is known that the frequency can be found by the formula:
f = c / λ, where f is the frequency of the transmitter
c – speed of light 300000 [km / s] = 3 * 10 ^ 8 [m / s]
λ – wavelength
f = 3 * 10 ^ 8 [m / s] / 15 [m] = 20 * 10 ^ 6 [Hz] = 20 [MHz]
Answer: the transmitter operates at 20 MHz
