Waves, Energy and Information - Benchmark Amplify

Front

What is energy transfer?

Back

Energy transfer is the process by which energy moves from one object or system to another, often resulting in a change in the state or motion of the objects involved.

Front

What happens to air particles when sound waves travel through them?

Back

Air particles vibrate and transfer energy to neighboring particles, causing them to also vibrate and transmit the sound.

Front

What is amplitude in sound waves?

Back

Amplitude is the height of the wave, which determines the loudness of the sound; higher amplitude means louder sound.

Front

What is wavelength in sound waves?

Back

Wavelength is the distance between two consecutive peaks or troughs in a wave, which affects the pitch of the sound.

Front

How do waves behave when they encounter a barrier?

Back

Waves can reflect, refract, or absorb when they encounter a barrier, changing their direction or energy.

Front

What is the relationship between sound waves and energy?

Back

Sound waves are a form of energy that travels through a medium (like air) and can be heard when they reach a listener's ears.

Front

Why are patterns important in digital communication?

Back

Patterns in digital communication help encode and decode messages, allowing devices to understand and transmit information accurately.

Front

What is the role of a receiver in digital communication?

Back

The receiver decodes the transmitted signals and converts them back into a form that can be understood, such as sound or text.

Front

What is the difference between loud and quiet sounds?

Back

Loud sounds have a higher amplitude, while quiet sounds have a lower amplitude.

Front

What is a sound wave?

Back

A sound wave is a type of mechanical wave that travels through a medium by vibrating particles.
