Try it on paper first. A hint, the key idea and the worked solution are here when you need them.

A sound in a pipe filled with helium has a frequency of $1600\ \text{Hz}$ and a wavelength of $0.6\ \text{m}$ . What is the speed of sound in the helium?

Need a reminder? The key ideaShow

Frequency $f$ (waves each second, in $\text{Hz}$ ), time period $T = \dfrac{1}{f}$ , wavelength $\lambda$ (compression to compression), and $v = f\lambda$ . The medium sets $v$ ; the source sets $f$ .

The worked solution

Have you tried it?

Work it out on paper first. It is fine to get stuck or make a mistake: that is how we learn. When you are ready, compare your working with the solution.
