waves

Question 1

what are the two categories for waves?

Answer 1

transverse
longitudinal

Question 2

examples of transverse waves

Answer 2

ripples on the surface of water

Question 3

example of longitudinal waves

Answer 3

sound waves travelling in air

Question 4

key fact about waves

Answer 4

all waves transfer energy form one place to another

Question 5

differences between longitudinal and transverse waves:

Answer 5

longitudinal waves’ oscillations are parallel to the waves direction
while transverse waves oscillations are perpendicular-90 degrees

transverse waves have oscillations that form crests and troughs whereas longitudinal waves have oscillations that create compressions and rarefactions

Question 6

what is refraction?

Answer 6

is the change of direction of a wave like light as it passes from one medium to another

Question 7

what is the definition of amplitude

Answer 7

is the maximum displacement of a point on the wave from its resting or undistributed position

Question 8

what is the definition of a wavelength?

Answer 8

is the distance from one point on a wave to the equivalent point on an adjacent wave

Question 9

what is the crest?

Answer 9

highest point

Question 10

what is the trough?

Answer 10

lowest point
