Question

question 16 of 20 : select the best answer for the question. 16. which of these frequencies falls in the range of radio frequency waves used by commercial radio broadcasting stations? a. 6,000,000 hz b. 600,000 hz c. 6,000 hz d. 60 hz mark for review (will be highlighted on the review page)

Explanation:

Commercial radio broadcasting stations typically use frequencies in the range of about 530 kHz to 1700 kHz (or 530,000 Hz to 1,700,000 Hz). Let's analyze each option:

• Option A: 6,000,000 Hz is 6 MHz, which is in the FM or other higher - frequency radio bands but not the typical AM commercial radio range (though still radio frequency). However, let's check other options.
• Option B: 600,000 Hz is 600 kHz, which is within the AM commercial radio broadcasting range (530 kHz - 1700 kHz).
• Option C: 6,000 Hz is 6 kHz, which is in the audio frequency range (not radio frequency for commercial broadcasting).
• Option D: 60 Hz is the frequency of AC power in many regions, not a radio frequency for broadcasting.

Among the options, 600,000 Hz (Option B) is within the range of radio frequencies used by commercial radio broadcasting stations (especially AM radio).

Answer:

B. 600,000 Hz
