Answer 8

the unit of motion that repeats

Question 9

Answer 9

a motion that repeats regularly, typically at a low speed

Question 10

what is a vibration

Answer 10

a quick back and forth harmonic motion

Question 11

what is the amplitude

Answer 11

a measurement of the size of a cycle

Question 12

what is a longitudinal wave

Answer 12

a wave whose oscillation are in the same direction as the wave travels

Question 13

what is a transverse wave

Answer 13

a type of wave with oscillations that are perpendicular to the direction the wave travels

Question 14

what is a standing wave

Answer 14

a resonance created by trapping a wave between boundaries that cause the wave to interfere with its own reflections

Question 15

what is the definition of reflection

Answer 15

when a wave changes by direction bouncing off a new medium

Question 16

what is the defintion for diffraction

Answer 16

when a wave encounters and changes its shape due to the boundary interaction

Question 17

is there a loss of energy in a reflection

Answer 17

no

Question 18

can something diffracted turn?

Answer 18

yes

Question 19

what is the defintion for an absorption

Answer 19

the place the sound wave is traveling absorbs the wave

Question 20

what is the defintion for a refraction

Answer 20

when a wave changes direction because a new medium has a different speed

Question 21

what happens during a refraction

Answer 21

the medium makes the wave go slower and bend
