Standing Waves & Constructive and Desturctive Interference

Question 1

Describe a standing wave pattern.

Answer 1

vibrational pattern created within a medium when the vibrational frequency of a source causes reflected waves from one end of the medium to interfere with incident waves from the source,

Question 2

Define nodes

Answer 2

positions along the medium that are standing still

Question 3

Define antinodes

Answer 3

positions along the medium that vibrate back and forth between upward displacement and downward displacement.

Question 4

What is a wave interference?

Answer 4

the phenomenon when two waves meet on the same medium.

Question 5

What are the two types of interferences?

Answer 5

constructive and destructive interference

Question 6

What’s constructive interference?

Answer 6

when two waves with the same displacement interfere on the medium.

Question 7

What’s destructive interference?

Answer 7

when tow waves with opposite displacements interferences on the medium.
