Sound Test

What is an example of a sound wave in everyday life?

• A person talking

• A light bulb shining

• A tree growing

• A car moving silently

What happens to the speed of sound when temperature increases?

• The speed of sound decreases with temperature.

• The speed of sound remains constant regardless of temperature.

• The speed of sound increases with temperature.

• The speed of sound fluctuates randomly with temperature.

What is the difference between longitudinal and transverse waves?

• Longitudinal waves have particle movement perpendicular to wave direction; transverse waves have particle movement parallel.

• Longitudinal waves have particle movement parallel to wave direction; transverse waves have particle movement perpendicular.

• Longitudinal waves are faster than transverse waves; transverse waves are slower.

• Longitudinal waves can travel through solids only; transverse waves can travel through liquids and gases.

What is the relationship between wavelength and pitch?

• Higher pitch corresponds to shorter wavelengths.

• Higher pitch corresponds to longer wavelengths.

• Wavelength has no effect on pitch.

• Pitch is independent of wavelength.

What is the formula for calculating the speed of sound?

• Speed = Frequency x Wavelength

• Speed = Distance / Time

• Speed = Mass / Volume

• Speed = Acceleration x Time

What is reflection in the context of sound waves?

• Reflection is the bending of sound waves as they pass through different mediums.

• Reflection is the absorption of sound waves by a surface.

• Reflection is the bouncing back of sound waves when they hit a surface.

• Reflection is the scattering of sound waves in multiple directions.

What is diffraction in sound waves?

• Diffraction is the bending of sound waves around obstacles.

• Diffraction is the reflection of sound waves off surfaces.

• Diffraction is the absorption of sound waves by materials.

• Diffraction is the amplification of sound waves in a medium.

What is the significance of sound wave frequency?

• Frequency determines the loudness of the sound.

• Frequency determines the pitch of the sound.

• Frequency determines the duration of the sound.

• Frequency determines the quality of the sound.

What is the decibel scale?

• A scale that measures temperature.

• A scale that measures the intensity of sound.

• A scale that measures distance.

• A scale that measures weight.

How does the speed of sound in air compare to that in water?

• Sound travels faster in air than in water.

• Sound travels at the same speed in air and water.

• Sound travels slower in air than in water.

• Sound does not travel in air.
