I WONDER - How Are Radio Waves Transmitted On The Radio?

The video explains how an antenna picks up signals and spreads them in all directions. These signals are then sent to a receiver, which separates the electric signals from the radio waves. Finally, the electric signals are converted back into sound by the speakers, allowing the sound to be heard.

What is the primary role of an antenna in radio signal transmission?

• To separate electric signals from radio waves

• To amplify electric signals

• To pick up and spread radio waves

• To convert sound into electric signals

What device is connected to the antenna to process the signals?

• Amplifier

• Speaker

• Transmitter

• Receiver

What is the main function of a receiver in the context of radio signals?

• To amplify the radio waves

• To separate electric signals from radio waves

• To spread radio waves in all directions

• To convert sound into radio waves

How are electric signals transformed back into sound?

• By spreading them in all directions

• By amplifying the signals

• Through the use of speakers

• By using a transmitter

What allows the sound to be heard after the electric signals are processed?

• The antenna

• The receiver

• The transmitter

• The speakers
