We shall calibrate the radiant power, P [W], of a laser by aiming it into a cup of black water and capturing narly all the radiant energy, Q [J], generated during an exposure time, t [s]. Measuring the temperature rise of the water will yield the power of the laser.

The radiant power P of the laser is 10 W.
