Which one of the following factors determines the pitch of a sound?

• The frequency of the sound wave

• The amplitude of the sound wave

• The distance of the sound wave from the source

• The speed of the sound wave

Sound waves that are beyond the range of human ear are known as ----

• Infrasonic

• Ultrasonic

• Audible

• Resonance

What is the relationship between amplitude and energy?

• The bigger the amplitude of the waves, the more energy the waves carry.

• The smaller the amplitude of the waves, the more energy the waves carry.

• Amplitude and energy are not related, they have no effect on each other

• Doubling the amplitude of the waves, reduces the amount of energy the wave carries by half.
