Behavior of Waves
Transmission
Transmission is when light rays pass through an object
Refraction
Refraction is when light rays bend to give an illusion of a bending material
Scattering
Scattering is when light hits a certain object that cause the light rays to move in all directions
Reflection
Reflection is when light rays bounce off an object
Absorption
Absorption is when light rays hit an object and the energy is absorbed and scattered a bit
Electromagnetic Waves
Digital
A digital wave/signal is sent in packets
Analog
An analog wave/signal is a continuous wave
Measurements
Hertz
The unit for frequency is hertz
Nanometer
Wavelengths are measured in nanometers (one billionth of a meter)
Waves
Mechanical Wave
A mechanical wave is a sort of wave that is only able to travel through a medium
Electromagnetic Wave
An electromagnetic wave is a wave that can travel in matter and doesn't need a medium to travel through
Wave
A wave transfers energy through a medium or empty space
medium
The space a wave moves through
Amplitude
Amplitude is the distance from the center line to the crest. it measure how tall a wave is
Crest and Trough
Crest- highest point of a wave
Trough- Lowest point of a wave
Wavelength
Wavelength is the space between two trough or crest points
Frequency
Frequency is the amount of waves that pass during a certain amount of time
Visible Light
Visible light is the part of the electromagnetic spectrum humans can see
Electromagnetic spectrum
Electromagnetic spectrum is the range waves that can travel through an empty space or matter/medium
