1.

The principle of superposition states that when two waves meet at a point, the resultant displacement is

the sum of the displacements of the individual waves
the product of the displacements
the larger of the two displacements
always zero
2.

A stationary wave is formed by

two waves travelling in the same direction
two waves of the same frequency and speed travelling in opposite directions
a single progressive wave
two waves of different frequency
3.

The distance between adjacent nodes in a stationary wave is

one wavelength
half a wavelength
a quarter of a wavelength
two wavelengths
4.

Diffraction is

the change in speed of a wave at a boundary
the superposition of two waves
the reflection of a wave
the spreading of a wave as it passes through a gap or round an edge
5.

For two sources to produce an observable interference pattern they must be

of different frequency
of very different amplitude
coherent
unpolarised
6.

8.

Destructive interference occurs where two coherent waves in phase at their sources arrive with a path difference of

an odd number of half wavelengths

any value
9.

A string fixed at both ends vibrates in its fundamental mode. The length of the string equals

one wavelength
