Exploring the Physics of Sound and Waves

What is the primary way sound waves travel through?

• Medium like air or water

• Solid objects only

• Vacuum

• Sound does not travel

What type of wave is a sound wave classified as?

• Surface wave

• Longitudinal wave

• Transverse wave

• Electromagnetic wave

How do microphones convert sound waves into audio data?

• By capturing electrical signals

• By detecting light waves

• By detecting changes in pressure

• By measuring temperature changes

What does the pitch of a sound correspond to?

• The sound's loudness

• The sound's intensity

• The frequency of the wave

• The amplitude of the wave

Why are some sounds too high or too low for humans to hear?

• Due to the sound's intensity

• Because of the sound's amplitude

• Owing to the frequency of the sound

• Because of the medium of propagation

What range of sound intensity can humans comfortably hear?

• 1 picowatt per square meter to 100 Watts per square meter

• 1 microwatt per square meter to 1 kilowatt per square meter

• 1 nanowatt per square meter to 1 milliwatt per square meter

• 1 picowatt per square meter to 1 Watt per square meter

How does the intensity of a sound wave affect its loudness?

• Intensity has no effect on loudness

• Loudness increases with intensity

• Higher intensity makes the sound softer

• Loudness is inversely proportional to intensity

What unit is used to measure the loudness of sounds?

• Hertz

• Watts

• Decibels

• Amperes

What happens to the pitch of a sound as the source moves towards you?

• It fluctuates rapidly

• It increases

• It decreases

• It remains the same

What effect describes the change in pitch due to the movement of a sound source?

• The Wavefront effect

• The Ripple effect

• The Doppler effect

• The Resonance effect
