Question

5) A medium radio wave band lies btw two wavelength 100 m and 1000m. Determine the corresponding frequency range (take the velocity of the wave to be 299.8X10^6m/s)​

Answer 1

Answer: The frequency (f) of a wave is related to its wavelength (λ) and velocity (v) by the equation:

f = v/λ

Given the wavelength range of 100 m to 1000 m for the medium radio wave band, we can calculate the frequency range as follows:

For the lower wavelength of 100 m:

f = v/λ = 299.8 × 10^6 m/s / 100 m = 2.998 × 10^6 Hz

For the higher wavelength of 1000 m:

f = v/λ = 299.8 × 10^6 m/s / 1000 m = 299.8 × 10^3 Hz

Therefore, the frequency range for the medium radio wave band is approximately 2.998 × 10^6 Hz to 299.8 × 10^3 Hz.
