Chapter 7: Transverse pulses

Question 1

Define displacement

Answer 1

Displacement is the distance the pulse has moved along a medium.

Question 2

What is amplitude?

Answer 2

The amplitude of a pulse is the maximum disturbance of a particle from its original/rest position.

Question 3

What is pulse length?

Answer 3

The pulse length is the distance between the starting point and ending point of a pulse.

Question 4

Define a pulse

Answer 4

A pulse is a single disturbance in a medium.

Question 5

What is the principle of superposition?

Answer 5

The principle of superposition states that when two pulses occur in the same place at the same time, the resulting pulse is the sum of the two interfering pulses.

Question 6

What is constructive interference?

Answer 6

Constructive interference occurs when the resulting amplitude of two or more pulses during interference is greater than the amplitude of the original pulses.

Question 7

What is destructive interference?

Answer 7

Destructive interference occurs when the resulting amplitude of two or more pulses during interference is less than the amplitude of the original pulses.
