waves physics
electromagnetic waves
transverse waves that transfer energy from the source of the waves to an absorber
displacement
the distance from the equilibrium position
wavelength
distance between 2 identical points in a wave train
Ws= f x Wl
time period
the time taken for 1 particle to complete a point
f=1/t
frequency
number of cycles per second
f=1/t
speed of light
3x10'8 m/s
waves
a process of energy transfer trhough oscillations without matter being transferred with it
longitudinal waves
Oscillations occur parallel to direction of travel
-> particles move up back and forth
-> sound waves
transverese wave
oscillaitions at right angle , perpendicular to direction of travel
particles move up and down
-> electromagnetic waves
-> microwaves , xrays
