Sample Questions

1multiple choice

What is the audible range of frequency for humans?

Show answer

20 Hz to 20,000 Hz

The human ear can detect sound frequencies from 20 Hz to 20,000 Hz (20 kHz). Sounds below 20 Hz are infrasonic, and sounds above 20 kHz are ultrasonic, both of which humans cannot hear.

2multiple correct

Which factors affect the speed of sound in air?

Show answer

Temperature, Humidity, Wind direction

Temperature, humidity, and wind direction all affect sound speed in air. Higher temperature increases speed, humidity increases speed, and wind can increase or decrease speed depending on direction. Amplitude and pressure do not affect sound speed.

3multiple choice

Ultrasonic waves have frequency:

Show answer

Above 20,000 Hz

Ultrasonic waves have frequencies above 20,000 Hz (20 kHz), which is beyond human hearing range. These waves are used in medical imaging, cleaning, and SONAR applications due to their high energy and directional properties.

4multiple choice

Why do we see lightning before hearing thunder?

Show answer

Light travels much faster than sound

Light travels at 3×10⁸ m/s while sound travels at only 330 m/s in air. This huge difference means light reaches us almost instantly while sound takes time to travel the same distance, causing the delay between seeing lightning and hearing thunder.
