Superposition and standing waves

Question 1

What is superposition?

Answer 1

The process by which two waves combine into a single wave when they overlap

Question 2

What are stationary/standing waves?

Answer 2

When two similar waves travel in opposite directions, they can pose to form a stationary wave made up of nodes and Antinodes

Question 3

What are nodes and anti-nodes?

Answer 3

Nodes are positions on a stationary wave which do not vibrate, the waves combine give zero displacement

Anti nodes or positions on a stationary wave where there is maximum displacement

Question 4

What is the difference between energy translation in stationary waves and progressive waves?

Answer 4

There is no energy translation in stationary waves

There is energy translation in the direction of the wave in progressive waves
