Read each question carefully and answer to the best of your ability. Show all your work for calculations.
1. Which of the following factors primarily affects the speed of sound in a medium?
Amplitude of the sound wave
Frequency of the sound wave
Temperature and elasticity of the medium
Wavelength of the sound wave
2. Sound waves are an example of what type of wave?
Transverse wave
Electromagnetic wave
Longitudinal wave
Surface wave
1. The speed of sound in air at 0°C is approximately m/s.
2. Sound travels faster in than in liquids or gases.
3. The of a medium refers to its resistance to deformation, which impacts the speed of sound.
1. The speed of sound increases as the temperature of the medium decreases.
True
False
2. The speed of sound is constant in all types of matter.
True
False
1. Explain why the speed of sound is generally faster in solids compared to gases.
2. A lightning strike occurs 5.0 km away. If the speed of sound in air is 343 m/s, how long after seeing the lightning flash will you hear the thunder? (Show your work)
Observe the diagram below showing sound waves. Which part of the wave represents a compression and which represents a rarefaction?
Match the term with its definition.
1. Elasticity
a. The maximum displacement or distance moved by a point on a vibrating body or wave measured from its equilibrium position.
2. Density
b. The property of a material to return to its original shape after deformation.
3. Amplitude
c. Mass per unit volume of a substance.
