Question 2

Trough

Answer 2

Lowest to

Question 3

Nano Meter

Answer 3

The distance from crest to crest or trough to trough

Question 4

Wave

Answer 4

Transfer of energy through and medium

Question 5

frequency

Answer 5

the number of cycles a wave completes in a period of time; the number of times something happens in a period of time

Question 6

period

Answer 6

one of the horizontal rows in the periodic table

Question 7

wavelength

Answer 7

the distance between one peak and the next on a wave

Question 8

amplitude

Answer 8

height or “strength” of a wave

Question 9

longitudinal wave

Answer 9

a wave that occurs when the particles of a medium move parallel to the direction of the wave

Question 10

electromagnetic spectrum

Answer 10

the full range of frequencies of electromagnetic waves

Question 11

transverse wave

Answer 11

a wave that occurs when the particles of a medium are displaced perpendicularly to the direction of the wave

Question 12

compression

Answer 12

occurs when rocks are squeezed by external forces directed toward one another to put stress on the rock, acting to decrease its volume or shorten its dimensions

Question 13

refraction

Answer 13

The decrease in density in a compressional or longitude way

Question 14

rarefraction

Answer 14

Decrease in density in longitudinal way

Question 15

reflection

Answer 15

to strike a surface and bounce back in the opposite direction (related word: reflection

Question 16

diffraction

Answer 16

the phenomenon exhibited by wave fronts that, passing the edge of an opaque body, are modulated, thereby causing a redistribution of energy within the front: it is detectable in light waves by the presence of a pattern of closely spaced dark and light bands (diffraction pattern) at the edge of a shadow.
