Prior Knowledge Questions about Waves

Multiple Choice

Waves are created by a vibration.

• True

• False

Multiple Choice

As a wave moves through a medium, the individual particles of the medium move

from the source of the wave to another location some distance away.

• True

• False

Multiple Choice

Waves are a means of transporting energy from one location to another without

actually displacing matter from one location to another.

• True

• False

Multiple Choice

Waves are a means of transporting energy from one location to another without

actually displacing matter from one location to another.

• True

• False

Properties of Waves

Multiple Choice

A wave is a disturbance that transfers:

• energy

• matter

Multiple Choice

Electromagnetic waves and Mechanical waves have identical properties.

• True

• False

You will be focusing on transverse waves since electromagnetic waves are transverse waves.

Labelling

Label the parts of the transverse wave.

Drag labels to their correct position on the image

wavelength

crest

trough

amplitude

Multiple Choice

What is the height of a wave?

• crest

• trough

• amplitude

Multiple Choice

What is the top of a wave?

• crest

• trough

• amplitude

Multiple Choice

What is the bottom of a wave?

• crest

• trough

• amplitude

Measuring Wavelengths

Measuring Amplitude

Finding Speed of a wave

Need to know frequency and wavelength...

Let's check it out...

Frequency is how many waves pass a certain point in 1 second.

Multiple Choice

The number of cycles in a given amount of time is ___________.

(sometimes called a wave train)

• diffraction

• 
  frequency

• refraction

Counting Waves (the wave train)

​If 3 waves pass a point in 1 second then the frequency (f) is 3/1 or 3 Hz.

Fill in the Blank

How many waves are in this wave train?

Fill in the Blank

What is the frequency of this wave? ____ Hz

Fill in the Blank

What is the speed of the wave? __ m/s

Multiple Choice

What is the frequency of this wave? _____ Hz

Hint...count the number of waves then divide that number by the time.

• 0.125 Hz

• 8 Hz

Multiple Choice

What is the wavelength of this wave? _____ m

Speed/velocity = wavelength x frequency

• 8 m

• 16 m

Multiple Choice

What is the speed of this wave? _____ m/s

Speed/velocity = wavelength (8 m) x frequency (0.125)

• 8 m/s

• 1 m/s
