Sound and Light Waves

Notebook Title:

Mr.

Miranda

●There are two types of waves we cover in Physics:

○Electromagnetic Waves are created by a fusion of electric and magnetic fields.
The light you see, the colours around you are visible because of electromagnetic
waves.

○Mechanical Waves are created by the vibrations of matter and result in the
transfer of energy.

■Mechanical Waves require a medium to travel through, which can take the
form of solids, liquids, and gases.

Types of Waves

Multiple Choice

Which type of wave requires a medium to travel through?

• Electromagnetic

• Mechanical

• Matter

• Magnetic

Reflection refers to when
a wave strikes a surface

and bounces off.

Properties of Sound Waves

Diffraction refers to when
waves are forced to bend

around a barrier.

Diffraction

Reflection

Properties of Sound Waves

Resonance is the ability of

sound waves to cause
objects at the same
frequency to vibrate.

Resonance

Pitch is the way frequency

is perceived in sound

waves. Higher frequency
sound waves have a higher

pitch and vice versa.

Pitch

Multiple Choice

An echo is an example of what type of property of waves?

• Reflection

• Diffraction

• Pitch

• Resonance

Multiple Choice

This is an example of what type of property of waves?

• Reflection

• Diffraction

• Pitch

• Resonance

Properties of
Sound Waves

The Doppler Effect refers to the an

increase (or decrease) in the pitch
(frequency) of an object as it gets

closer (or farther) from the listener.

An example of this is ambulance

sirens. The closer you are, the

higher the pitch!

Dropdown

According to the Doppler Effect, the ​

Select answer

you are to the source of a sound, the smaller the wavelength and ​

Select answer

the pitch.

Properties of
Light Waves

Refraction is the tendency of of

waves to change direction of their

waves when passing through a
medium with different density.

This is the property that

microscopes and telescopes use to

work!
