science waves

Question 1

A traveling disturbance that carries energy from one point to another

Answer 1

wave

Question 2

the material through which a wave travels

solids, liquids, gasses

Answer 2

medium

Question 3

highest point on a transverse wave

Answer 3

crest

Question 4

lowest point on a transverse wave

Answer 4

trough

Question 5

distance between two corresponding points on a wave

Answer 5

wavelength

Question 6

measure of the height of a wave

Answer 6

amplitude

Question 7

waves in which the motion of the medium is parallel to the direction of the wave

(comperssion and rarefaction)

Answer 7

longitudinal wave

Question 8

waves in which the motion of the medium is at right angles or side to side to the direction the energy is moving

Answer 8

transverse wave

Question 9

where particles of the medium are densely packed
areas of high pressure

Answer 9

compressions

Question 10

where particles of the medium are loosely packed
areas of low pressure

Answer 10

rarefraction

Question 11

the number of waves passing a specific point in one second

Answer 11

frequency

Question 12

what units are used to measure frequency?

Answer 12

hertz (Hz)

Question 13

(of a material or article) allowing light to pass through so that objects behind can be distinctly seen.

(window)

Answer 13

transparent

Question 14

(of a substance) allowing light, but not detailed shapes, to pass through; semitransparent.

(sunglasses, stain glasses window)

Answer 14

translucent

Question 15

not able to be seen through; not transparent.

Answer 15

opaque

Question 16

The bouncing off of a wave when it strikes a boundary

Answer 16

reflection
(mirror, echo)

Question 17

the bending of waves through a medium due to change in wave speed as the wave passed into a new medium
(transparent or translucent)

Answer 17

refraction
(change of an object underwater)

Question 18

the bending of waves around the edge of an obstacle

Answer 18

diffraction
(hearing a television in a different room, rainbow)

Question 19

the overlapping of waves occupying the same space

Answer 19

wave interference

Question 20

when waves align to build on each other and make a larger wave

Answer 20

constructive interference
(wave will build)

Question 20

two waves overlap in such a way that their crests align with each other’s troughs, resulting in a smaller amplitude or even complete cancellation of the waves

Answer 20

destructive interference
(wave will be destroyed

Question 21

what property of sound affects the volume

Answer 21

amplitude

Question 22

what property of sound affects the pitch

Answer 22

frequency

Question 22

what units measure the volume of sound?

Answer 22

decibels (dB)

Question 23

waves that require a medium to travel

Answer 23

mechanical waves (transmits energy)

Question 24

waves that can travel through space

Answer 24

electromagnet wave (transmits energy)

Question 25

which wave has the shortest wavelength and the highest frequency?

Answer 25

gamma rays

Question 26

which rays have the longest wavelengths and the shortest frequency?

Answer 26

radio waves

Question 27

which part of the electromagnet spectrum are you able to perceive

Answer 27

visible light

Question 28

represented by a wave which changes over time and continuous range of values

Answer 28

analog signals (AM and FM radios Older televisions Landline phones Speedometers)

Question 29

Time separated into signals that convert data into binary code

Answer 29

Digital signals (Cell phones High definition televisions Bluetooth and WI-FI Morse code)

Question 30

which signal is better? digital or analog, why?

Answer 30

Digital signals are better because they are more reliable and clear. There is less noise and distortion due to less inference.
