Quantization of Energy 1. According to the classical theory of physics, the energy radiated by a blackbody
approaches infinity as the wavelength of the emitted light approaches zero.
a. Why was this considered a problem for classical physics?
b. Max Planck solved this problem in 1900. What was the key to the solution?
c. How does Planck's assumption solve the "ultraviolet catastrophe"?

Point charges q1=+2.00μc and q2=−2.00μc are placed at adjacent corners of a square for which the length of each side is 1.50 cm . point a is at the center of the square, and point b is at the empty corner closest to q2. take the electric potential to be zero at a distance far from both charges. part a what is the electric potential at point a due to q1 and q2? express your answer with the appropriate units.
