Delta X into Delta p
h/4pie
Delta p
M delta v
h/ 4pie
Delta x * delta p = delta x * m delta v = 0.527 × 10^-34
Ratio of change in position and change in momentum
Delta Xa / delta Xb = delta Pb/ delta Pa

Bohr atomic model
Angular momentum of an orbit
nh /2pie
Ionization energy
Energy required to move an electron from ground state to infinity .
E 1 = - K.E = - I.E
Excitation energy
Enery required to move an electron from groud state to any other excited state .
E .E = En - E1
Separation energy
Amount of energy required to move sn electron from any excited state to infinity
S.E = - En
Energy Difference
En2 - En1 = 13.6z² ( 1/n1² - 1/n2²
Time & Frequency
T = d/s = 2pie r / v
Frequency = V / 2pier
Total lines in emmision spectrum
[ (n2 - n1 )( n2 -n1 +1)] / 2
Ryberg frequency
Freq . = CRz² ( 1 / n1² - 1/ n2²)
DE Broglie concept
Wavelength is inversely proportion to momentum
● Wavelength = h /P = h / mv = h / underroot 2m K.E
De broglie cpncept
When charge particle is accelerated the K.E
K.E = QV
WAVELENGTH = h/ underroot 2mQV
De broglie concept
Wavelength for electron
= whole ubderroot 150 / v = 12.25/ v
Circumference = n wavelength
