1
Q

A
When two progressive waves with the same frequency (and ideally same amplitude), travelling in opposite directions, superpose.
2

A
Points on a stationary wave that always have zero amplitude. Two adjacent nodes are half λ apart.
3

A
Points on a stationary wave that always have maximum displacement. Two adjacent antinodes are half λ apart.
