Do mechanical waves travel faster or slower in more dense media?

Lunna [17]

When waves travel from one medium to another the frequency never changes. As waves travel into the denser medium, they slow down and wavelength decreases. Part of the wave travels faster for longer causing the wave to turn. The wave is slower but the wavelength is shorter meaning frequency remains the same

An agricultural sprinkler distributes water in a circular pattern of radius 100 ft. It supplies water to a depth of e^-r feet pe

Elan Coil [88]

A circle of radius $R$ ft has area $\pi R^2$ sq ft. For any fixed $R$ , water will reach a depth of $e^{-R}$ ft. You can think of the total volume of water supplied within a radius $R$ of the sprinkler as the volume of the "cylinder" with "height" given by $e^{-r}$ for some $0$ .

This volume is

$\displaystyle\int_0^{2\pi}\int_0^Rre^{-r}\,\mathrm dr\,\mathrm d\theta=2\pi(1-e^{-R}(R+1))$
