Dual nature of matter and radiation
Important formulae
1. Maximum Kinetic Energy
eVo=mV2max/2
Vo = Stopping Potential
2. Energy(E) of a particle of mass (m) moving
velocity (v) and momentum (p) E=1/2mv2=p2/2m
3. Momentum of a particle
P=mv=√2mE = √2mqV
where q is the charge of the particle and V is the accelerating P.D. for a charged particle.
4. Expression for de Broglie wavelength
λ=h/p=h/mv=h/√2mE=h/√2mqV
Associated with the moving particle
5. Be Broglie wavelength the electron λ=1.227nm/√V => λ=1.227nm/√V
Accelerated under a potential difference ((A0 = 10-10m, 1nm=10-9m))
6. Be Broglie wavelength gas molecule λ=h/mcrms=h/√3mKT
Where K=Boltzman constant
7. Number of photons emitted
Per second by a source
n = power/energy
