Sound Test

Front

What is the speed of sound in water?

Back

1,500 m/s.

Front

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

Back

Sound travels slower in air than in water.

Front

What is reflection in the context of sound waves?

Back

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

Front

What is the relationship between wavelength and pitch?

Back

Higher pitch corresponds to shorter wavelengths.

Front

What happens to the speed of sound when temperature increases?

Back

The speed of sound increases with temperature.

Front

What is the definition of density in relation to sound transmission?

Back

Density is the mass per unit volume of a substance; denser materials can transmit sound faster.

Front

What is diffraction in sound waves?

Back

Diffraction is the bending of sound waves around obstacles.

Front

What is interference in sound waves?

Back

Interference is the interaction between two or more sound waves that combine to form a new wave.

Front

What is refraction in the context of sound?

Back

Refraction is the change in direction of sound waves as they pass from one medium to another.

Front

What is the decibel scale?

Back

The decibel scale measures the intensity of sound.
