Wave Properties Flashcards
What are the two types of waves?
Transverse and longitudinal Waves
What do Waves do?
Waves transfer energy, however they don’t transfer any matter
What does a wave do to travel?
Waves vibrate or oscillate
What is maximum displacement of a wave called?
Amplitude
What is the very top of a wave called?
The crest
What is the distance of one entire oscillation called?
It is called wavelength
What is the very bottom of a wave called?
Trough
What does displacement mean?
How far from equilibrium point has the wave oscillated.
What is a time period?
The time it takes for one complete oscillation
What is the equation of frequency?
1/time period
What is frequency measured in?
Hertz (Hz)
What is the equation for wave speed?
Frequency x Wavelength
What must you convert wavelength into?
You must convert it into Ms
What is a transverse wave?
Oscillations perpendicular to the direction of energy transfer
What is a longitudinal wave?
Oscillation that are parallel to the direction of energy transfer
What is compression?
When waves are closer together
What is rarefraction?
When waves are further apart
True or false:
Longitudinal do not require a medium to travel in
False
Which colour has the longest wavelength?
Red
Which colour has the shortest wavelength?
Violet
What is black?
Abscense of light
What is white?
A combination of all wavelengths
What is the colour of something dependent on?
The wavelengths hitting it and the properties of the object. This will determine which wavelengths will be absorbed, transmitted or reflected.
What is absorption?
When a wave losses its energy as it transmits into a material
What is transmission?
When a wave travels into a new medium or travels through a medium
What is reflection?
The change in direction of a wavefront.
What do transparent and translucent object do?
They transmit a lot of light
Do transparent objects transmits all the light?
No they transmit most of it.
