Take this Mini-Quiz to check your understanding of the lesson material.

1. What is a source of infrasound waves?

Vibrations of the Earth

Various small animals

Radio and television

2. What is the approximate range of wavelengths of sound that a human can hear?

34.4 m to 344 km

17.2 m to 1.72 cm

1 cm to 0.03 mm

3. What equation is used to determine the ultrasound wavelength?

λ = v/f

λ = vf

λ = 0.034 mm

If you got all three correct, you are on your way to becoming a Champion in Physics. If you had problems, you had better look over the material again.
