y

–

x

graph of a transverse wave shows successive crests at

x = 0.15\,\text{m}

and

x = 0.55\,\text{m}

. A

y

–

t

graph taken at

x = 0

shows that two successive crests pass the point

0.04\,\text{s}

apart. The speed of the wave is a)

5\,\text{m\,s}^{-1}

20\,\text{m\,s}^{-1}

10\,\text{m\,s}^{-1}

16\,\text{m\,s}^{-1}
