Learning outcomes

Waves transfer energy

Frequency

Worksheet

Drawing waves

This is the number of waves which pass a point every second.

Model

Complete the worksheet. You have 15 minutes.

Both types of wave can be drawn like this:

There are two types of wave

Can I have some volunteers to make a model of each of the wave types?

Sound

What are waves?

peak

By the end of the lesson I will be able to:

Describe the two main types of wave (grade C)

Identify the main parts of a wave (grade C)

If two waves are moving the same speed the one with the shortest wavelength will have the biggest frequency

Any other examples?

What are the 4 labelled parts on this wave?

What happens to sound when we increase the amplitude?

What happens when we change the frequency?

What about light?

trough

Direction of travel

Copy neatly into your books
