What type of signals were you using on the last occasion when you used a hand-held remote control to change the channel on your television?
- A.
Electrical pulses
- B.
Microwaves
- C.
Infrared
- D.
Radio waves
- E.
All of the above
Correct Answer
C. InfraredExplanation
Infrared signals are commonly used in hand-held remote controls to change the channel on a television. These signals are transmitted in the form of infrared light waves, which are not visible to the human eye. When the remote control sends an infrared signal, it is picked up by a sensor on the television, which then processes the signal and changes the channel accordingly. This type of signal is preferred for remote controls because it is reliable, low-cost, and does not interfere with other electronic devices in the vicinity.Rate this question:

- E.
All of the above
Correct Answer
B. Radio wavesExplanation
Radio waves are the type of signals used between a radio and a radio tower. Infrared signals are not typically used for long-range communication, and microwaves are generally used for shorter-range communication such as in microwave ovens. Electrical pulses may be used for digital communication, but radio waves are the most common and effective type of signals used in radio communication. Therefore, the correct answer is radio waves.Rate this question:
