5.2/5.3 Sound and Light (SOL)

Front

What is a translucent object?

Back

A translucent object allows some light to pass through but not enough to see clearly through it. Examples include frosted glass and wax paper.

Front

How does light travel?

Back

Light travels in a straight path.

Front

What is the difference between transparent, translucent, and opaque materials?

Back

Transparent materials allow all light to pass through (e.g., clear glass), translucent materials allow some light to pass through (e.g., frosted glass), and opaque materials do not allow light to pass through at all (e.g., wood).

Front

What happens to light when it passes through a prism?

Back

Light is refracted, which means it bends and separates into different colors, creating a rainbow effect.

Front

What is refraction?

Back

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

Front

What is reflection?

Back

Reflection is when light bounces off a surface, such as a mirror.

Front

What is an example of a transparent object?

Back

An example of a transparent object is clear glass.

Front

What is an example of an opaque object?

Back

An example of an opaque object is a brick wall.

Front

What is the role of polarized lenses in sunglasses?

Back

Polarized lenses reduce glare from surfaces like water or roads by blocking certain light waves.

Front

What is the speed of light?

Back

The speed of light in a vacuum is approximately 299,792 kilometers per second (or about 186,282 miles per second).
