Unit 5, Section 1: Wave Properties

Question 1

wave

Answer 1

any disturbance that transfers energy

Question 2

mechanical waves

Answer 2

waves that move through matter

Question 3

medium

Answer 3

the matter a wave travels through

Question 4

vacuum

Answer 4

a space where no matter is present

Question 5

transverse waves

Answer 5

waves that travel perpendicular to the source of energy

Question 6

longitudinal waves

Answer 6

waves that travel parallel to the vibrations

Question 7

compressions

Answer 7

when waves get closer together

Question 8

rarefactions

Answer 8

gaps between compressions when they get farther apart

Question 9

surface waves

Answer 9

a combination of transverse and longitudinal waves making a circle

Question 10

Electromagnetic Radiation

Answer 10

the energy transferred through space by Electromagnetic waves, without a medium

Question 11

crest

Answer 11

top point of a wave

trough

Answer 12

bottom point of a wave

Question 13

wavelength

Answer 13

the distance a wave travels before repeating itself
measured in meters
Lambda (λ)

Question 14

Amplitude

Answer 14

distance between highest crest of lowest trough and the resting position
