Question

Paul made a diagram to compare and contrast radio waves that are used for communication and for broadcasting. Which labels belong in the areas marked X, Y, and Z? X: May use LF, HF, and UHF waves Y: Travels at the speed of light Z: May use MF and VHF waves X: Travels at the speed of light Y: May use LF, HF, and UHF waves Z: May use MF and VHF waves X: May use MF and VHF waves Y: May use LF, HF, and UHF waves Z: Uses radio waves with long wavelengths X: Uses radio waves with long wavelengths Y: May use LF, HF, and UHF waves Z: May use MF and HF waves Mark this and return

Answer 1

Answer: (A) "X: May use LF, HF, and UHF waves

Y: Travels at the speed of light

Z: May use MF and VHF waves"

Answer 2

X: May use LF, HF, and UHF waves Y: Travels at the speed of light Z: May use MF and VHF waves

Step-by-step explanation:

The radio waves are a type of special phenomena a transverse waves. These waves satisfy the wave properties that include:

• The application of the wave equation:
  `v = f\lambda`
• They travel in the medium
• They carry energy in motion
• They have associations and peaks and crests.
• They can be interfered
• They can be reflected (although sound waves are reverberated)

However, added to the list, radio waves are a special kind of waves as they have different frequencies such as low frequency (LF), High frequency (HF) and Ultrahigh Frequency (UHF). Thus, the first option is correct.
