Standing waves and Superposition

How do standing waves form?

Superposition of two waves travelling in opposite directions with the same speed and wavelength.

What is a node?

A position on a wave with an amplitude that stays at 0.

What is an antinode?

A position on a wave that has a maximum amplitude.

How can a standing wave be formed using one wave?

Reflect the wave back (resonant frequencies)

When are two points on a wave in phase?

On the same point of the wave cycle (moving in the same direction/ doing the same thing at the same time)

When are two points on a wave out of phase?

On different points of the wave cycle.

When are two points on a wave in antiphase?

On the opposite point of the wave cycle (moving in the opposite direction/ doing the opposite thing at the same time)

What is the phase difference?

The amount one wave lags behind another.

What is one wave shown as?

360 ^o (2π radians)
