- Q1
What remains constant in an AM broadcast?
speech
music
amplitude
frequency
30s - Q2
Which type of radio broadcast has a greater broadcast range?
Infrared Wave
FM Radio Wave
Visible Light
AM Radio Wave
30s - Q3
Why does AM radio focus mainly on news and talk show programs?
AM radio has fixed wave amplitude and constant frequency
AM radio has a constant bandwidth than FM radio
AM radio has higher bandwidth than FM radio
AM radio has a lower bandwidth than FM radio
30s - Q4
What is the advantage of FM over AM?
FM is less susceptible to noise because noise affects amplitude, whereinformation is “stored” in an FM signal.
FM is less costly than AM.
FM is less susceptible to noise because the information in an FM signal is transmitted through varying the frequency, and not the amplitude.
FM can be heard over long distances than AM.
30s - Q5
What made FM radio ideal for playing music?
FM can be heard over long distances than AM.
FM is less susceptible to noise because the information in an FM signal is transmitted through varying the frequency, and not the amplitude.
FM is less costly than AM.
FM is less susceptible to noise because noise affects amplitude, where information is “stored” in an FM signal.

30s - Q8
What does FM stand for?
Fair Modulation
Frequency Modulation
Front Modulation
Frequency Moderation
30s - Q9
What is the frequency range of FM radio?
88 MHz – 108 MHz
118 MHz – 128 MHz
