5.6 Light Test Review

Front

What is refraction?

Back

Refraction is the bending of light as it passes from one medium to another, causing objects to appear larger or distorted when viewed through water or glass.

Front

What does it mean for a material to be transparent?

Back

A transparent material allows light to pass through it without significant scattering, enabling clear visibility of objects behind it.

Front

Why do we see lightning before we hear thunder?

Back

We see lightning before we hear thunder because light travels faster than sound through the atmosphere.

Front

What happens to light rays when they are reflected?

Back

When light rays are reflected, they bounce off a surface at the same angle at which they hit it.

Front

What is the difference between reflection and refraction?

Back

Reflection is the bouncing back of light from a surface, while refraction is the bending of light as it passes through different materials.

Front

What is the speed of light compared to the speed of sound?

Back

Light travels much faster than sound; in air, light travels at approximately 299,792 kilometers per second, while sound travels at about 343 meters per second.

Front

What is a wavelength?

Back

A wavelength is the distance between two consecutive peaks (or troughs) of a wave, which determines the wave's color in the case of light.

Front

What is an example of a transparent material?

Back

Clear window glass is an example of a transparent material that allows light to pass through.

Front

What is the role of light in photosynthesis?

Back

Light provides the energy needed for plants to convert carbon dioxide and water into glucose and oxygen during photosynthesis.

Front

What is the law of reflection?

Back

The law of reflection states that the angle of incidence is equal to the angle of reflection.
