CBSE Class 12 Physics Formulae Dual Nature Of Matter And Radiation Notes

CBSE Class 12 Physics Formulae Dual nature of matter and radiation. Learning the important concepts is very important for every student to get better marks in examinations. The concepts should be clear which will help in faster learning. The attached concepts will help the student to understand the chapter and score better marks in the examinations. 

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
