Stationary waves

Question 1

1st harmonic

Answer 1

2 nodes and 1 antinode

Question 2

2nd harmonic

Answer 2

3 nodes and 2 antinode

Question 3

What is a node

Answer 3

A point along a standing wave with 0 amplitude

Question 4

What is an antinode

Answer 4

A point along the wave with max amplitude

Question 5

What is the distance between a node and antinode

Answer 5

1/4 of a wave

Question 6

Difference between progressive and stationary wave 1

Answer 6

Each point along a progressive wave has equal amp but amp varies for standing wave

Question 7

Difference between progressive and stationary wave 2

Answer 7

Adjacent points on progressive waves vibrate with diff phase but all particles between nodes in standing waves vibrate in place

Question 8

Difference between progressive and stationary wave 3

Answer 8

Energy is transferred through space in progressive waves but not in the case of standing waves

Question 9

What is t in equation V = √’T/u

Answer 10

Tension

Question 11

What is u in equation V = √’T/u

Answer 11

Mass per unit length

Question 12

Fundamental frequency

Answer 12

Lowest freq to get standing wave
