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. The 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.
