1) The spectral emittance of a radiating cavity is maximal at a wavelength of 32 µm. The
temperature is then changed so that the total power radiated in the cavity triples. Calculate
the new temperature of the cavity.
2) A proton is moving at a speed of 0.923c. If the kinetic energy is tripled, by how much does
the speed increase?
