Question 1

wave?

Answer 1

transfer of energy

Question 2

how is energy transferred through a wave?

Answer 2

vibration of oscillating particles colliding

Question 3

diagram of transverse wave?

Answer 3

see image

Question 4

diagram of a longitudinal wave?

Answer 4

see image

Question 5

frequency?

Answer 5

The number of waves passing a point in a certain time (1 wave per/sec = 1 hertz)

Question 6

amplitude (a)?

Answer 6

Distance from wave vertex to centre line

Question 7

wavelength and symbol?

Answer 7

the distance from one point (e.g. Crest) on wave to the same point on the next wave (measured in metres) - -λ

Question 8

period?

Answer 8

how long wavelength pass point

Question 9

compression?

Answer 9

region of longitudinal waves particles closest together

Question 10

transverse?

Answer 10

particles displace perpendicular to wave direction light wave

Question 11

longitudinal?

Answer 11

particles displace parallel to wave direction sound wave

Question 12

rarefaction?

Answer 12

region of longitudinal wave particles furthest apart

Question 13

changes in frequency amplitude change what hear?

Answer 13

hi freq = high pitch

hi amplitude = loud more energy

Question 14

speed of sound affected by medium and which?

Answer 14

sound particles bouncing together closer particles faster energy louder
can travel through all mediums (solid liquid gas)
can’t travel through space/vacuum no matter
slowest in gases less particles
faster water slightly closer
fastest solids particles closest

Question 15

speed wave equation?

Answer 15

V = λf

Question 16

wave frequency equation?

Answer 16

f = v/λ

Question 17

speed sound?

Answer 17

330 m/s
