Question 1

What is a wave

Answer 1

a disturbance that travels thru a medium (medium carries the wave)

waves transport energy, not matter

Question 2

types of waves

Answer 2

mechanical - not capable of transmitting thru vacuum (require medium)

electromagnetic - transmit thru vacuum (magnetic and electric fields)

Question 3

transverse vs longitudinal waves

Answer 3

transverse - displacement of medium is perpendicular to direction of motion

longitudinal - displacement of medium is parallel

Question 4

amplitude determines ______ of a physical wave

Answer 4

size - how high wave is
loudness- bigger amplitude, louder sound
intensity- bigger amplitude, intense electromagnetic wave

Question 5
