The ability to do work
Energy
A disturbance that transfers energy from place to place
Wave
The material through which a wave travels through
Medium
The lowest point of a wave
Trough
The highest point of a wave
Crest
The repeated back-and-forth or up-and-down motion
Vibration
What are the properties of waves
Frequency, speed, wavelength, amplitude
The maximum distance the particles of a medium can move from their rest positions
Amplitude
The distance between two corresponding parts of a wave
Wavelength
The number of complete waves that pass a given point in a certain amount of time
Frequency
Frequency is measured in units called _______
Hertz
A wave that transfers electric and magnetic energy
EM wave
The energy that is transferee through space by EM waves
EM radiation
The complete range of EM waves placed in order of increasing frequency
EM spectrum
EM waves that you can see
Visible light
A material that transmits most of the light that strikes it
Transparent
A material that scatters light as it passes through it
Translucent
A material that reflects or absorbs all of the light that strikes it
Opaque
Colored substances ythat are used to color other materials
Pigment
Two primary colors combined in equal amounts
Secondary colors
Any two colors that combine to form white light
Complementary colors
Three colors that combine to make any other color
Primary colors
Occurs when an object or wave bounces back off a surface throught which it cannot pass
Reflection
All waves obey the…. Which states they the angle of incidence is equal to the angle of reflection
Law of reflection
