An acoustic sensor sends a sound pulse through a liquid coupling layer and into a ceramic tile.
| Medium | Speed of sound in the medium in m/s\text{m/s}m/s |
|---|---|
| liquid coupling layer | 1900 |
| ceramic tile | 6000 |
The wavelength of the sound in the liquid coupling layer is 0.95 mm.
Calculate the wavelength of the sound in the ceramic tile.
