PS.6.3.2 Waves Flashcard

Front

What is scattering in relation to light rays?

Back

Scattering is the process where light rays deviate from their original path due to obstacles like dust or gas molecules.

Front

What does it mean for a material to be transparent?

Back

A transparent material transmits all light, allowing objects behind it to be seen clearly.

Front

What is a translucent material?

Back

Translucent materials scatter light and allow partial visibility through them.

Front

Define refraction in the context of light or sound.

Back

Refraction is the bending of light or sound as it passes through different mediums or materials.

Front

What type of solar radiation is absorbed by the ozone layer?

Back

The ozone layer absorbs ultraviolet radiation to prevent harmful rays from reaching Earth's surface.

Front

What is reflection in terms of light behavior?

Back

Reflection is the bouncing back of light rays when they hit a surface.

Front

What is the difference between opaque and transparent materials?

Back

Opaque materials do not allow any light to pass through, while transparent materials allow all light to pass through.

Front

Give an example of a translucent material.

Back

Frosted glass is an example of a translucent material.

Front

What happens to light when it hits a reflective surface?

Back

When light hits a reflective surface, it bounces back, which is known as reflection.

Front

What is the role of the ozone layer in relation to UV radiation?

Back

The ozone layer protects life on Earth by absorbing most of the sun's harmful ultraviolet radiation.
