Module 4 - 4.4.4 Stationary Waves

Question 1

Stationary Waves

Answer 1

Store Energy

Question 2

Stationary Waves are formed when

Answer 2

a wave reflects then interferes with itself

Question 3

Node

Answer 3

The particle doesn’t vibrate (the displacement is zero)

Question 4

Antinode

Answer 4

The particle vibrates with maximum amplitude

Question 5

The distance between 2 adjacent nodes

Answer 5

λ/2

Question 6

The distance between an adjacent node and antinode

Answer 6

λ/4

Question 7

Stationary Waves in tubes (3)

Answer 7

• the progressive wave travels down the tube and is reflected at the closed end
• this produces two progressive waves travelling in opposite directions
• the waves interfere to produce a stationary wave

Question 8

Locations of Nodes and Antinodes in Stationary Waves

Answer 8

Nodes = closed end
Antinodes = open end
