Sound Waves Quiz

What are the properties of sound waves?

• Color, texture, weight, and size

• Taste, smell, sight, and touch

• Frequency, amplitude, wavelength, and speed

• Temperature, pressure, density, and volume

Explain the characteristics of sound waves.

• Sound waves are longitudinal waves that require a medium to travel, they can be described by their frequency, amplitude, wavelength, and speed.

• Sound waves are transverse waves that do not require a medium to travel

• Sound waves travel at the speed of light

• Sound waves are only described by their frequency

What is the speed of sound in air at 20°C?

• 500 m/s

• 250 m/s

• 150 m/s

• 343 m/s

How does the speed of sound differ in water compared to air?

• Slower in water

• The same in water and air

• Faster in water

• Depends on the temperature of the water

Describe the process of reflection of sound waves.

• The process of reflection of sound waves involves the bouncing back of sound waves when they hit a surface.

• The process of reflection of sound waves involves the absorption of sound by the surface it hits.

• Sound waves reflect by changing their frequency when they hit a surface.

• Reflection of sound waves occurs when the waves pass through the surface without any change.

Give an example of an application of sound waves in medical imaging.

• MRI imaging

• Ultrasound imaging

• X-ray imaging

• CT scan imaging

What is the speed of sound in steel?

• 10000 m/s

• 1500 m/s

• 6100 m/s

• 340 m/s

Discuss the application of sound waves in sonar technology.

• Sonar technology uses light waves to detect objects underwater.

• Sonar technology uses radio waves to detect objects underwater.

• Sonar technology uses magnetic waves to detect objects underwater.

• Sonar technology uses sound waves to detect objects underwater.

Explain how the speed of sound changes with temperature in air.

• The speed of sound increases with an increase in temperature in air.

• The speed of sound decreases with an increase in temperature in air.

• The speed of sound is not affected by temperature in air.

• The speed of sound remains constant regardless of the temperature in air.

What is the effect of altitude on the speed of sound?

• The speed of sound increases with altitude.

• The speed of sound decreases with altitude.

• The speed of sound is not affected by altitude.

• The speed of sound remains constant regardless of the altitude.
