What is a sound wave?

Back

A sound wave is a type of mechanical wave that propagates through a medium (like air, water, or solids) as a result of vibrations. It is characterized by its frequency, wavelength, and amplitude.

Front

What happens to the volume of a sound wave as it travels further away from the source?

Back

The volume of a sound wave decreases as it travels further away from the source due to the spreading of the wave energy over a larger area.

Front

What is pitch in relation to sound waves?

Back

Pitch is the perceived frequency of a sound wave; higher frequencies correspond to higher pitches, while lower frequencies correspond to lower pitches.

Front

What is the resultant force?

Back

The resultant force is the overall force acting on an object when all individual forces are combined. It determines the object's motion.

Front

How do you determine the direction of the resultant force?

Back

The direction of the resultant force is determined by the direction of the larger force when forces of different magnitudes act in opposite directions.

Front

What is an independent variable in a hypothesis?

Back

An independent variable is the factor that is changed or manipulated in an experiment to observe its effect on the dependent variable.

Front

What is a dependent variable in a hypothesis?

Back

A dependent variable is the factor that is measured or observed in an experiment, which is affected by changes in the independent variable.

Front

What is a controlled variable?

Back

A controlled variable is a factor that is kept constant throughout an experiment to ensure that the results are valid.

Front

What is a digital wave?

Back

A digital wave is a representation of a signal that can take on discrete values, often used in digital communication systems.

Front

What is the relationship between energy and amplitude in sound waves?

Back

The energy of a sound wave is directly related to its amplitude; higher amplitude means higher energy and louder sound.
