Hot Objects and the Quantization of Energy

Potential energy of person walking up steps increases in stepwise, quantized manner 

The constant h is called Planck s constant and has a value of 6.626 X 10 joule-second (J-s). 

Calculate the energy (to one significant figure) of one quantum of electromagnetic radiation whose frequency is 5 X 10 s Can Ihis radiation produce a 

In 1900 a German physicist named Max Planck (1858-1947) solved the problem by making a daring assumption He proposed that energy can be either released or absorbed by atoms only in discrete chunks of some minimum size. 

Planck gave the name quantum (meaning fixed amount ) to the smallest quantity of energy that can be emitted or absorbed as electromagnetic radiation. He proposed that the energy, E, of a single quantum equals a constant times the frequency of the radiation  

Consider the notes that can be played on a piano. In what way is a piano an example of a quantized system In this analc, would a violin be continuous or quantized
