Waves and Sound

Question 1

wave

Answer 1

disturbance in time and space that transports energy through matter in space without transporting matter

Question 2

crest

Answer 2

the high point of a wave

Question 3

trough

Answer 3

the low point of a wave

Question 4

amplitude

Answer 4

wave height from the centerline of the wave; higher amplitude=more energy

Question 5

mechanical waves

Answer 5

waves that travel through matter

Question 6

types of mechanical waves

Answer 6

circular, transverse, and longitudinal

Question 7

circular waves

Answer 7

waves in which the particles of the medium move in an elliptical pattern

Question 8

transverse waves

Answer 8

waves in which the particles of the medium vibrate in an up and down motion perpendicular to the motion of the wave

Question 9

longitudinal waves

Answer 9

(compression waves) waves in which the particles of the medium vibrate back and forth along the path that the wave travels

Question 10

reflection

Answer 10

interaction that occurs when a wave “bounces back” after striking a barrier

Question 11

refraction

Answer 11

the bending of a wave as it passes from one medium to another

Question 12

diffraction

Answer 12

the bending of waves around a barrier or through an opening

Question 13

interference

Answer 13

when two waves of the same frequency arrive at the same place at the same time and overlap each other

Question 14

resonance

Answer 14

the transfer of energy between objects that can vibrate at the same natural frequency

Question 15

sound waves

Answer 15

sounds produced by vibration

Question 16

pitch

Answer 16

how high or low one perceives a sound to be

Question 17

frequency

Answer 17

number of waves that go by in one second

Question 18

loudness

Answer 18

how loud or soft one perceives a sound to be
