Standing Waves

Question 1

How are standing waves created?

Answer 1

Pulses, which moves a string perpendicular to the d of motion
Which occur when 2 waves interfere from opposite directions

Question 2

What do the waves look like in standing waves

Answer 2

The wave reflects from the point and then have an inverted amplitude

Question 3

Why is it called standing waves?

Answer 3

There are some points that look like they are standing still

Question 4

What is a node?

Answer 4

Points of no displacement (amplitude)
The standing still part

Question 5

Why do nodes look like they’re not moving?

Answer 5

Due to the destructive interference between both waves

Question 6

What is an antinode?

Answer 6

Points of max displacement (amplitude)

Question 7

Why do antinodes move?

Answer 7

Due to the constructive intereference between both waves
