Mechanical and Electromagnetic Wave

What makes a mechanical wave?

• A disturbance in matter that carries energy from one place to another. 
• Hertz (Hz)
• The combination of two or more waves. 
• Longitudinal Waves

What does a mechanical wave travel through?

• A piece of wood
• A medium
• Nothing
• Air

• centimeters
• Hertz (Hz)

Amplitude is...

• A wave in which the vibration of the medium is parallel to the direction the wave travels
• the greatest distance waves move from rest.
• A longitudinal wave that travels through a medium and causes your eardrums to vibrate
• A technique for determining distance. 

Combination of two or more waves that combine into a single wave

•  Interference
• Destructive
• Constructive
• Two types of Interference

How many types of waves are there?

• One
• Two
• Three
• Four

Destructive 

• Constructive
• Increases amplitude
• Decreases amplitude
• Interference

Increases amplitude

• Interference
• Destructive 
• Decreases amplitude
• Constructive

A wave in which the vibration of the medium is parallel to the direction the wave travels

• Transverse waves
• Decreases amplitude
• Longitudinal waves
• Interference

A swimmer floating in the water moves up and down as the waves pass by her. The distance the swimmer moves up and down would be

• the wavelength
• twice the wavelength
• twice the amplitude
• the amplitude
