$470 \text{ m s}^{-1}$

$0.0021 \text{ m s}^{-1}$

$3400 \text{ m s}^{-1}$

$340 \text{ m s}^{-1}$

Only transverse waves

Only longitudinal waves

Both transverse and longitudinal waves

Neither type of wave

One wavelength

Half a wavelength

A quarter of a wavelength

Two wavelengths

A stationary wave transfers energy along the string while a progressive wave merely stores it in place

A progressive wave has fixed nodes and antinodes, whereas a stationary wave has none of these features

A stationary wave stores energy; a progressive wave transfers it

All points along a progressive wave oscillate with exactly the same amplitude at every instant

$100 \text{ Hz}$

$400 \text{ Hz}$

$80 \text{ Hz}$

$200 \text{ Hz}$

A whole number of wavelengths

An odd number of half wavelengths

Half a wavelength only

A quarter of a wavelength

They have the same amplitude but may differ in frequency and phase over time

They have the same frequency and a constant phase difference

They emit light of exactly the same colour and brightness at all times

They are positioned exactly one wavelength apart from one another

$0.30 \text{ mm}$

$30 \text{ mm}$

$3.0 \text{ mm}$

$0.83 \text{ mm}$

When the gap is very much larger than the wavelength of the incoming wave

When the gap is very much smaller than the wavelength of the incoming wave

The amount of diffraction does not depend on the size of the gap at all

When the gap is about the same size as the wavelength

$d\sin\theta = n\lambda$

$d\cos\theta = n\lambda$

$\frac{d}{\sin\theta} = n\lambda$

$d\tan\theta = n\lambda$

$48.6^\circ$

$41.8^\circ$

$33.6^\circ$

$66.4^\circ$
