Using the equation v = wavelength * frequency.
We know v, its the speed of light.
Given frequency = 900 kHz. So solving for wavelength, we get (3 x 10^8 m/s)/(900 x 10^3 Hz)
= 333 m

Understanding FM Radio Frequency and Wavelength
FM radio broadcasts at a frequency of 900 kHz. To find the corresponding wavelength, we can use the formula that relates frequency and wavelength in a vacuum:
Formula for Wavelength
Wavelength (λ) = Speed of Light (c) / Frequency (f)
Where:
- Speed of Light (c) ≈ 3 x 10^8 meters per second
- Frequency (f) = 900 kHz = 900,000 Hz (since 1 kHz = 1,000 Hz)
Calculating the Wavelength
Using the values:
- λ = (3 x 10^8 m/s) / (900,000 Hz)
- λ = (3 x 10^8) / (9 x 10^5)
- λ = 333.33 meters
Thus, the wavelength that corresponds to a frequency of 900 kHz is approximately 333 meters.
Conclusion
So, the correct answer to the question is:
- Option (a): 333 m
This calculation illustrates how the frequency of radio waves is inversely related to their wavelength; as frequency increases, wavelength decreases.
