Matching Frequency Ranges to Applications
This question requires matching specific frequency ranges from List I to their common applications in List II.
Solution Steps
- Analyze Item a (300 kHz - 3 MHz): This frequency range, known as Medium Frequency (MF), is primarily used for AM Broadcasting. Therefore, 'a' matches 'iii'.
- Analyze Item b (430 THz - 750 THz): This range represents extremely high frequencies, corresponding to infrared and visible light. This spectrum is the basis for Optical Communication technologies. Therefore, 'b' matches 'iv'.
- Analyze Item c (30 GHz - 300 GHz): These frequencies fall into the millimeter wave bands (part of SHF and EHF). They are commonly utilized in applications requiring high bandwidth, such as Satellite Communication and radar systems. Therefore, 'c' matches 'ii'.
- Analyze Item d (30 MHz - 300 MHz): This range, known as Very High Frequency (VHF), is standard for FM Broadcasting and TV transmission. Therefore, 'd' matches 'i'.
Final Matching
Based on the analysis:
- a - iii (AM Broadcasting)
- b - iv (Optical communication)
- c - ii (Satellite communication)
- d - i (FM Broadcasting, TV)
This corresponds to the matching: a - iii, b - iv, c - ii, d - i.
