MOBILE RADIO PROPAGATION Quiz

What is radio wave propagation?

• The behavior of radio waves as they travel from one point to another.

• The process of planting radio waves in the ground

• The study of radio waves in outer space

• The use of radio waves to cook food

How do radio waves travel through the atmosphere?

• By bouncing off the ground

• By line of sight and reflection off the ionosphere

• By traveling through water vapor in the atmosphere

• By following the Earth's magnetic field

Explain the concept of line-of-sight communication.

• Direct visibility between transmitting and receiving antennas without obstruction

• Communication through underground cables

• Communication using satellite signals

• Communication through sound waves

What is the difference between reflection and diffraction in radio wave propagation?

• Reflection involves slowing down of radio waves, while diffraction involves speeding up of radio waves.

• Reflection involves straight-line propagation of radio waves, while diffraction involves circular propagation of radio waves.

• Reflection involves absorption of radio waves, while diffraction involves amplification of radio waves.

• Reflection involves bouncing back of radio waves, while diffraction involves bending of radio waves around obstacles.

How does multipath interference affect mobile radio communication?

• It causes the signal to travel faster

• It can cause signal cancellation or reinforcement.

• It only affects the audio quality

• It has no impact on mobile radio communication
