3.2 P Waves Absorption, Transmission, Reflection (Kelly)

Front

What is reflection in terms of light and sound?

Back

Reflection is when light or sound bounces off a surface instead of being absorbed or transmitted.

Front

What does it mean for light to be absorbed?

Back

Absorption occurs when light is taken in by a material and does not pass through or reflect off it.

Front

What is transmission in the context of light?

Back

Transmission is when light passes through a material without being absorbed or reflected.

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, changing its speed.

Front

What happens to sound when it is reflected?

Back

When sound is reflected, it bounces back off a surface, allowing us to hear echoes.

Front

Can you give an example of light being transmitted?

Back

An example of light transmission is sunlight passing through a clear window.

Front

What is an example of sound absorption?

Back

An example of sound absorption is a sponge soaking up water, similar to how soft materials absorb sound.

Front

What is the difference between reflection and refraction?

Back

Reflection is bouncing off a surface, while refraction is bending as it passes through a different medium.

Front

What is an example of refraction?

Back

An example of refraction is a straw appearing bent when placed in a glass of water.

Front

What materials are good at absorbing sound?

Back

Soft materials like carpets and curtains are good at absorbing sound.
