(a)[2]
Describe the conditions that must be satisfied for two waves to form a stationary wave.
(b(i))[1]
A stationary wave on a string contains nodes and antinodes. The distance from a node to the neighbouring antinode is $6.0\,\text{cm}$. State what is meant by a node.
(b(ii))[1]
Calculate the wavelength of the two waves forming the stationary wave.
(b(iii))[1]
State the phase difference between the particles at two adjacent antinodes of the stationary wave.
(b)
A stationary wave on a string includes nodes and antinodes. The gap between a node and the next antinode is $6.0\,\text{cm}$.
