ITS ABOUT QUANTANIZATION OF ENERGY

1. Quantization of Energy FUNDAMENTALS OF SPECTROSCOPY

2. An electron can radiate or absorb energy as radiations only in limited amounts or bundles called quanta. This is known as quantization energy.

3. INTRODUCTION Have you ever wondered about the small differences in the location of the electrons? How are the charges shifting? Everything is linked with quantum theory. Max Planck, a German physicist, studied the emission of lights by hot objects. Why this phenomenon occurs, all depends upon the quantization of energy.

4. QUANTIZATION OF ENERGY-DEFINATION An electron can radiate or absorb energy as radiation only in limited amounts or bundles called quanta. This is known as the quantization of energy. Quantization is a physical quantity that only has discrete values. The energy levels of electrons of metals can be quantized.

5. The energy levels of electrons of metals can be quantized.

6. WHAT IS QUANTA? Quanta can be defined as the minimum quantity of energy that can either be gained or lost by an electron. Hence, if you see the energy levels of an electron, you can see that an atom needs to gain or lose energy to reach the next level or fall to the level. Absorption of heat or light helps the electrons gain energy to go to the next energy level or fall to lower energy levels.

7. FORMULA Through the experiment of emission of light from hot objects, Planck devised a formula. He showed that the quantity of radiant energy emitted or absorbed by an object is directly proportional to the frequency of the radiation E = h v Where, E = Energy of quantum radiation, in joules v = Frequency h = A fundamental constant called Planck’s constant

8. T he value of Planck’s constant is taken as h = 6.626 × 10⁻³⁴ J⋅s. The huge energy change results in emission or absorption of high frequency, whereas the small energy changes result in low emission or absorption of frequency. The energy present in a system must decrease or increase in the units of h x v.
