Explanation / Answer

Hello,
          Please find the answer attached as under. Please give a thumbs up rating if you find the answer useful! Have a rocking day ahead!

3.

Wave velocity = 3 x 108 m/s. Wavelength = 40m. Therefore, frequency = velocity/wavelength = 7.5MHz

Wave velocity = 3 x 108 m/s. Wavelength = 5m. Therefore, frequency = velocity/wavelength = 60MHz

Wave velocity = 3 x 108 m/s. Wavelength = 0.08m. Therefore, frequency = velocity/wavelength = 3.75GHz

4.

Lower frequency = 902 MHz. Upper frequency = 928 MHz

Bandwidth = frequency range = 928 - 902 = 26MHz
