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...

What happens when two waves interfere?

constructive- combining of waves where it is bigger than the original, destructive- resulting...

What is a standing wave?

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