PS4.1-4.2 Waves Properties & Behaviors

Front

What is amplitude in a wave?

Back

Amplitude is the maximum distance that a wave's particles move from their rest position. It determines the loudness of sound waves.

What happens to sound waves when they are absorbed?

Back

When sound waves are absorbed, they lose energy and do not bounce back. This is why sound can become quieter when it hits soft materials.

How do orcas use reflection of sound waves?

Back

Orcas use echolocation, which involves reflecting sound waves off objects to locate prey.

What is the relationship between amplitude and sound loudness?

Back

Higher amplitude means louder sound, while lower amplitude means softer sound.

What does it mean for an object to reflect light?

Back

An object reflects light when it bounces back the light waves that hit it, which allows us to see the object.

What is refraction in waves?

Back

Refraction is the bending of waves as they pass from one medium to another, changing speed and direction.

What is the definition of wavelength?

Back

Wavelength is the distance between two consecutive crests or troughs in a wave.

Front

What is the difference between transmission and absorption of waves?

Back

Transmission is when waves pass through a material, while absorption is when waves are taken in by the material and converted to other forms of energy.

Front

What is the crest of a wave?

Back

The crest is the highest point of a wave, representing the maximum displacement of the wave from its rest position.

Front

What is the trough of a wave?

Back

The trough is the lowest point of a wave, representing the minimum displacement of the wave from its rest position.
