Waves - Coggle Diagram
Force and waves
Materials and waves
Any substance that wave moves through is medium
Waves that transfer energy through matter are mechanical waves
the direction that the wave travels is perpendicular or right angel to the direction of the disturbance
the wave travels in the same direction as the disturbance.
Measuring wave properties
A crest is the highest point of a wave
A trough is the lowest point
amplitude is the distance between a line through the middle of a wave, crest or through
wavelength is the distance from a wave crest to the other.
frequency is the number of waves passing a fixed point in a certain amount of time
When frequency increases, more wave crests pass the fixed point by the second.
How to calculate the wave speed?
Waves behave in predictable ways
The bouncing back of a wave after it strikes a barrier is called reflection
Refraction is the bending of a wave as it enters a new medium at an angle other than 90 degrees.
Interference is meeting and combining of waves
Diffraction is the spreading out of waves through an obstacle.
A wave is a disturbance that transfers energy from one place to another.
