Mechanical vs Electromagnetic
What is similar about both mechanical and electromagnetic waves?
They carry energy, not matter
What is the top of a transverse wave called?
The crest
When waves pass through a given point or medium
Transmission
What type of interference when the crest of one wave meets and the trough of another meets?
Destructive interference
Where does light enter the eye?
Through the pupil
Are Electromagnetic or Mechanical waves sound waves?
Mechanical
Measurement from crest to crest or trough to trough on a transverse wave
wavelength
Plane mirrors and other smooth surfaces do what?
Reflect
When the crest of two waves meet is a what?
Constructive interference
What controls the size of the pupil and how much light enters the eye?
The iris
Which waves do not require a medium?
Electromagnetic waves
The middle of the wave to either the crest or trough
The amplitude
