Question

We can hear sounds of every frequency.

• A. True
• B. False

Answer 1

The correct option is B False

1. The audible frequency range for humans lies between 20Hz-20KHz.
2. The waves of frequency below 20 Hz are infrasonic waves.
3. The waves of frequency more than 20KHz are ultrasonic.
4. We cannot hear infrasonic and ultrasonic waves.
5. So, we cannot hear every frequency.

Hence, the statement of the question is false.
