Understanding AM and FM Radio

What is the primary way AM radio transmits information?

• By changing the frequency of the wave

• By changing the amplitude of the wave

• By changing the color of the wave

• By changing the speed of the wave

Why does FM radio generally provide better sound quality than AM radio?

• Because it can travel longer distances

• Because it uses higher power

• Because it changes the amplitude

• Because it is less susceptible to noise

What allows AM radio to travel longer distances at night?

• Its lower power consumption

• Its higher frequency

• Its ability to change amplitude

• Its ability to bounce off the ionosphere

What type of interference is AM radio more susceptible to?

• Optical interference

• Electrical interference

• Thermal interference

• Magnetic interference

Why is FM radio less affected by electrical interference compared to AM radio?

• Because it can bounce off the ionosphere

• Because it operates at a lower frequency

• Because it uses frequency modulation

• Because it uses amplitude modulation
