Question 1

What is a pulse?

Answer 1

A single disturbance that is propagated from one point to another in a medium

Question 2

A medium

Answer 2

The substance

Question 3

Define propagated

Answer 3

the process by which a disturbance travels through a medium

Question 4

Transverse pulse

Answer 4

Is perpendicular to the direction of propagation of the pulse

Question 5

Equilibrium position

Answer 5

The rest position of the medium when there is no disturbance

Question 6

Amplitude

Answer 6

The maximum displacement of a particle from its equilibrium position

Question 7

pulse length

Answer 7

width of the pulse

Question 8

what is Superposition

Answer 8

This is the combining of pulses, to form a single pulse with a greater amplitude of smaller amplitude

Question 9

The phenomenon that is observed during superposition

Answer 9

phenomenon of interference

Question 10

Constructive interference

Answer 10

This is when the two pulses amplify each other to result in a single pulse with a greater amplitude

Question 11

Destructive interference

Answer 11

This is when two pulses weaken/cancel each other and result in a single pulse with a smaller amplitude or no pulse

Question 12

Transverse waves

Answer 12

A wave whose oscillations are perpendicular to the direction of the wave’s advance

Question 13

Wave

Answer 13

Consists of a regular successive of disturbances or pulses that originate at one point in a medium propagated through the medium

Question 14

Wavelength

Answer 14

distance between two successive points that are in phase (Meters)

Question 15

Frequency

Answer 15

Number of cycles passing a fixed point (Hertz)

Question 16

Crest

Answer 16

highest point on the wave

Question 17

Trough

Answer 17

The lowest point on the wave

Question 18

Longitudinal waves

Answer 18

Longitudinal waves are waves in which the vibration of the medium is parallel \ to the direction the wave travels.

Question 19

Compressions

Answer 19

Parts of the spring where coils are compressed together, the crests of a wave

Question 20

Rarefactions

Answer 20

Parts of the spring where the coil is stretched out, the trough of a wave

Question 21

Pitch

Answer 21

refers to how high or low a sound is

Question 22

loudness

Answer 22

depends on amplitude, the greater the amp, the louder the sound

Question 23

Quality

Answer 23

is how a sound can have the same pitch and loudness but still sound different
