Waves Coogle By Quinn Bernthal
Waves transfer energy
a wave is a disturbance
a wave is a disturbance that transfers energy from one place to another
forces and waves
forces can start a disturbance, sending a wave through a material
materials and waves
a medium is any substance that a wave can move through
mechanical waves transfer energy through matter
energy and waves
it is the energy that travels in a wave
waves can be classified by how they move
transverse waves
in a transverse wave, the direction of the wave traveling is perpendicular or at right angles to the direction of the disturbance
longitudinal waves
in a longitudinal wave, the wave travels in the same directions as the disturbance
compression is how close the waves are to each other
waves have measurable properties
waves have amplitude, wavelength and frequency
measuring wave properties
A crest is the highest point or peak of a wave
A trough is the lowest point or valley of a wave.
wavelength and frequency are related
Graphing wave properties
amplitude is the distance between a line through the middle of a wave and a crest or through
amplitude indicates how much energy a wave is carrying
wavelength is the distance from one wave crest to the very next crest
frequency is the number of waves passing a fixed point in a certain amount of time
wave speed can be measured
speed=wavelength*frequency (S=nF)
waves behave in predictable ways
waves interact with materials
reflection
The bouncing back of a wave after it strikes a barrier is reflection!!!!
Diffraction
Diffraction is the spreading out of waves through an opening or around the edge of an obstacle
Refraction
Refraction is the bending of a wave as it enters a new medium at an angle other than 90 degrees
Waves interact with other waves
waves adding together
The waves crests and troughs are aligned briefly, which means they are joined up exactly
Waves cancel each other out
The energy is in one wave joins another and gets subtracted sometimes
