Question

A person can hear a sound of frequency

• A. 1 Hz
• B. 1000 Hz
• C. 200KHz
• D. 5MHz

Hint:

Humans can typically hear sounds between 20 Hz and 20 kHz. Sounds outside this range are either infrasonic or ultrasonic.

Answer 1

The Correct Option is B

Let’s break down the solution step by step: Step 1:
The range of audible sound frequencies for humans is typically from 20 Hz to 20,000 Hz (20 kHz).

Step 2:
1 Hz is too low, as it falls below the audible range.
1000 Hz is within the human hearing range.
200 KHz and 5 MHz are both too high and fall outside the audible range.


Step 3:
Thus, the correct answer is (2) 1000 Hz.
