Question

Match List I with List II:

List I	List II
(A) AM Broadcast	(I) 88 – 108 MHz
(B) FM Broadcast	(II) 540 – 1600 KHz
(C) Television	(III) 3.7 – 4.2 GHz
(D) Satellite Communication	(IV) 54 – 890 MHz

Choose the correct answer from the options given below:

• A. A-II, B-III, C-I, D-IV
• B. A-II, B-I, C-IV, D-III
• C. A-IV, B-III, C-I, D-II
• D. A-I, B-III, C-II, D-IV

Hint:

 Remember:
• AMisin the KHz range.
• FMis in the lower MHz range.
• Television spans most of the MHz range.
• Satellite communication operates in the GHz range.

Answer 1

The Correct Option is B

To match the items in List I with List II, we analyze the frequency ranges:

• AM Broadcast: AM radio waves have a frequency range of 540 to 1600 KHz, which falls into the category (II).
• FM Broadcast: FM radio waves are transmitted in the frequency range 88 to 108 MHz, corresponding to (I).
• Television: Television signals typically range from 54 to 890 MHz, matched to (IV).
• Satellite Communication: Satellite communications occur in the GHz range, specifically 3.7 to 4.2 GHz, which corresponds to (III).

Thus, the correct matching is:

A-II, B-I, C-IV, D-III

Answer 2

AM Broadast →540−1600KHz 
FM Broadcast →88−108MHz 
Television →54−890MHz 
Salellite communication →3.7−4.2GHz 
∴ A-II, B-I, C-IV, D-III
