Physics; Wave definitions

Question 1

Pulse

Answer 1

single disturbance in a medium that moves from one point to another

Question 2

Transverse pulse

Answer 2

occurs when particles move perpendicular with direction of wave

Question 3

Medium

Answer 3

material along which the pulse moves

Question 4

Rest position

Answer 4

position where no pulse | disturbance moves through

Question 5

Amplitude

Answer 5

maximum displacement | disturbance from rest position

Question 6

Pulse length

Answer 6

distance from start to end point of pulse

Question 7

peak

Answer 7

highest point in curve in the “positive pulse”

Question 8

trough

Answer 8

lowest point in curve in the “negative pulse”

Question 9

pulse speed

Answer 9

v=d/t

Question 10

longitudinal pulses

Answer 10

move in a direction parallel to direction of the wave

Question 11

superposition

Answer 11

2 pulses meet simultaneously at the same point in the medium

Question 12

interference

Answer 12

effect each pulse has on each other

Question 13

wave

Answer 13

regular sequence of pulses

Question 14

transverse wave

Answer 14

wave where the disturbance of the medium is perpendicular to the propagation direction (direction being travelled to)

Question 15

wavelength

Answer 15

distance between 2 successive points in phase “distance covered”

Question 16

frequency

Answer 16

number of whole waves that move past a fixed point (equilibrium) in 1 second

Question 17

period

Answer 17

time taken to complete one full wave (motion of wave)
