An oceanographer conducts an experiment to determine the speed of acoustic waves in seawater using a sonar transit-time technique.
From their measurements, the oceanographer calculates the speed of the acoustic waves to be 1465 m s-1.
The accepted reference value for the speed of sound in seawater at this specific temperature and salinity is 1505 m s-1.
Calculate the difference between the oceanographer's experimental value and the accepted value as a percentage of the accepted value.
