1. 1Why can a satellite radio signal cross the vacuum between Earth and a satellite?

   1. A.Its wave requires a continuous gas path.
   2. B.Its wave carries air from the transmitter.
   3. C.Its wave needs no material medium.Correct answer: C
   4. D.Its wave follows a physical conductor.

   Explanation: NASA states that electromagnetic waves "do not require a medium to propagate." Radio communication therefore works across a vacuum; matter or a continuous wire is unnecessary.

2. 2Which fields are coupled in a propagating electromagnetic wave?

   1. A.Changing electric and magnetic fieldsCorrect answer: A
   2. B.Static electric and gravitational fields
   3. C.Changing magnetic and acoustic fields
   4. D.Static magnetic and gravitational fields

   Explanation: NASA explains, "A changing magnetic field will induce a changing electric field and vice-versa—the two are linked." This distinguishes an electromagnetic wave from static fields and sound.

3. 3A radio carrier completes one million cycles each second. What is its frequency?

   1. A.1 kHz
   2. B.1 MHzCorrect answer: B
   3. C.1 GHz
   4. D.1 THz

   Explanation: NASA defines frequency: "One wave—or cycle—per second is called a Hertz (Hz)". One million cycles per second is one megahertz.

4. 4What does the wavelength of a radio signal measure?

   1. A.Time needed for one complete oscillation
   2. B.Number of oscillations passing per second
   3. C.Strength of the received electric field
   4. D.Distance between successive wave crestsCorrect answer: D

   Explanation: NASA states, "The distance between crests is the wavelength." The other descriptions concern period, frequency, and field strength.

5. 5Which broad microwave band designation includes 6 GHz?

   1. A.C-bandCorrect answer: A
   2. B.Ku-band
   3. C.Ka-band
   4. D.X-band

   Explanation: ESA lists "C-band (4–8 GHz)". Thus 6 GHz is C-band under this broad designation, rather than Ku, Ka, or X.

   Reference: Satellite frequency bands — C-band

6. 6A component is specified for a 14 GHz satellite link. Which broad band designation applies?

   1. A.C-band
   2. B.S-band
   3. C.Ku-bandCorrect answer: C
   4. D.Ka-band

   Explanation: ESA identifies "Ku-band (12–18 GHz)". A 14 GHz link falls within that range.

   Reference: Satellite frequency bands — Ku-band

7. 7Under ESA's broad microwave band designations, which range is Ka-band?

   1. A.4–8 GHz
   2. B.12–18 GHz
   3. C.18–26 GHz
   4. D.26–40 GHzCorrect answer: D

   Explanation: ESA gives "Ka-band (26–40 GHz)". The competing ranges represent other microwave bands, rather than Ka.

   Reference: Satellite frequency bands — Ka-band

8. 8Which capability is associated with Ku-band satellite systems in ESA's description?

   1. A.Low-data-rate links using satellite phones
   2. B.High-capacity services with smaller antennasCorrect answer: B
   3. C.Protected government radar imaging links
   4. D.Short-range vehicle collision radar links

   Explanation: ESA says Ku-band "supports high-capacity services with smaller antennas". The other choices confuse Ku-band with the L-, X-, and K-band applications described on the same page.

   Reference: Satellite frequency bands — Ku-band

9. 9Which band does ESA describe as particularly suited to high-throughput satellite internet?

   1. A.L-band
   2. B.S-band
   3. C.Ka-bandCorrect answer: C
   4. D.X-band

   Explanation: ESA lists "High-Throughput Satellite (HTS) internet" among typical Ka-band uses. L-, S-, and X-band applications in the comparison do not match that stated broadband role.

   Reference: Satellite frequency bands — Ka-band, Typical uses

10. 10Which satellite band does ESA value for low rain fade and wide coverage in large-scale communications?

    1. A.C-bandCorrect answer: A
    2. B.K-band
    3. C.Ka-band
    4. D.Ku-band

    Explanation: For C-band, ESA states, "It is valued for its low rain fade and wide coverage". Higher-frequency alternatives have different propagation tradeoffs.
