Match List-I with List-II.
| List-I | List-II | ||
| Service | Frequency bands | ||
| (A) | Television | (I) | 3.7 - 4.2 GHz |
| (B) | FM Broadcast | (II) | 840 - 935 MHz |
| (C) | Cellular Mobile Radio | (III) | 54 - 890 MHz |
| (D) | Satellite Communication | (IV) | 88 - 108 MHz |
Choose the correct answer from the options given below:
Answer & explanation
Correct answer: option 1
The correct answer is Option (1) → (A)-(III), (B)-(IV), (C)-(II), (D)-(I)
Each communication service is given its own frequency band, and the bands rise in frequency from broadcast services to satellite links.
(A) Television — this matches (III) 54 - 890 MHz. TV signals use the VHF and UHF bands, which together run from 54 MHz to 890 MHz.
(B) FM Broadcast — this matches (IV) 88 - 108 MHz. FM radio stations are placed in the narrow band from 88 MHz to 108 MHz.
(C) Cellular Mobile Radio — this matches (II) 840 - 935 MHz. Mobile phones use the UHF band around 900 MHz.
(D) Satellite Communication — this matches (I) 3.7 - 4.2 GHz. Satellite links need microwaves that pass through the ionosphere; the downlink band is 3.7 GHz to 4.2 GHz.
NCERT (2026-27):
Radio Waves – “… TV waves range from 54 MHz to 890 MHz. The FM (frequency modulated) radio band extends from 88 MHz to 108 MHz. Cellular phones use radio waves to transmit voice communication in the ultrahigh frequency (UHF) band.”
Microwaves – “Microwaves (short-wavelength radio waves), with frequencies in the gigahertz (GHz) range, are produced by special vacuum tubes (called klystrons, magnetrons and Gunn diodes).”
