6th Grade Science Unit 3- Waves

Front

What is a wave?

Back

A wave is a disturbance that transfers energy from one place to another without transferring matter.

Front

What are the two main types of waves?

Back

The two main types of waves are mechanical waves (which require a medium, like sound waves) and electromagnetic waves (which do not require a medium, like light waves).

Front

What is the speed of a wave?

Back

The speed of a wave is the distance the wave travels per unit of time.

Front

What happens to light when it passes from one medium to another?

Back

When light passes from one medium to another, it can change speed and direction, a phenomenon known as refraction.

Front

What is frequency in relation to waves?

Back

Frequency is the number of waves that pass a point in one second, measured in hertz (Hz).

Front

What is wavelength?

Back

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

Front

How does the energy of a wave relate to its frequency?

Back

Higher frequency waves carry more energy than lower frequency waves.

Front

What is reflection in terms of waves?

Back

Reflection is when a wave bounces back after hitting a barrier.

Front

What is refraction?

Back

Refraction is the bending of a wave as it passes from one medium to another due to a change in speed.

Front

What is the relationship between sound waves and their medium?

Back

Sound waves travel faster in solids than in liquids, and faster in liquids than in gases.
