Chapter 5, Problem 39A

Interpretation Introduction

Interpretation:

Plank’s quantum concept needs to be explained as it relates to energy lost or gained by matter.

Concept introduction:

The mass, velocity is related to de Broglie wavelength using the Planck’s constant as follows:

$\text{λ=}\frac{\text{h}}{\text{mυ}}$

The above equation is known as de Broglie equation.

Answer to Problem 39A

Planck concluded that quanta is a matter that can loss or gain energy in small amounts.

Explanation of Solution

Planck concluded that matter can gain or loss energy in small amounts is termed as quanta. A quantum is also known as latest possible amount of energy which an atom can gain or lose.

Conclusion

Planck suggested that energy emitted by hot objects was quantized.
