Answer:
To find the wavelength of the radio waves from a station broadcasting at 78 MHz, we can use the formula:
Wavelength (λ) = Speed of light (c) / Frequency (f)
Given that the speed of light (c) is 3 × 10^8 m/s and the frequency (f) is 78 MHz, we can convert the frequency to hertz (Hz) by multiplying it by 10^6:
f = 78 MHz = 78 × 10^6 Hz
Now, we can plug in the values into the formula:
Wavelength (λ) = Speed of light (c) / Frequency (f)
Wavelength (λ) = (3 × 10^8 m/s) / (78 × 10^6 Hz)
Wavelength (λ) = 3.84615385 × 10^(-6) m
Therefore, the wavelength of the radio waves from a station broadcasting at 78 MHz is approximately 3.846 × 10^(-6) meters.
