What is a wave?

a disturbance that transmits energy through matter or space.


Calculate the speed of a wave.

wavelength/period


What do waves transfer?

energy


What is the difference between a mechanical wave and an electromagnetic wave?

electromagnetic does not require a medium, disturbance in electric and magnetic fields.


What is the connection between vibrations and transformations of energy?

simple harmonic motion faces that push in opposite directions


How do particles move in transverse and longitudinal waves?

transverse perpendicular , longitudinal parallel


How do particles move in a surface wave?

circles


How can you measure the amount of particle vibration?

period


How can you determine wave speed?

frequency x wavelength


What does the speed of a wave depend on?

medium


What do you know about ALL electromagnetic waves as they travel through empty space?

they travel at the same speed


What is the relationship between frequency and pitch?

pitch is determined by frequency


Understand the Doppler effect?

an observed change in frequency of a wave when the source/observer is moving


Understand how waves behave. Reflection, refraction, and diffraction.

reflection the bouncing back of a wave when it meets a surface, diffraction the bending of a wave as it passes an edge or opening, refraction the bending of waves as they pass from one medium to another


What happens when two waves interfere?

constructive combining of waves where it is bigger than the original, destructive resulting wave is smaller


What is a standing wave?

a vibration of a system in which some points remain fixed while others between vibrate
