Given :
Mass of particle = 100g = 0.1kg
Velocity = 100 cm/s = 1 m/s
To Find :
de Broglie wavelength associated with the macroscopic particle.
Solution :
❒ Wavelength associated with any moving microscopic or macroscopic particle is inversely proportional to the momentum.
- Momentum is measured as the product of mass and velocity.
de Boglie equation :-
- Ek denotes kinetic energy
- q denotes charge of particle
- m denotes mass
- v denotes velocity
- V denotes accelerating potential
- h denotes plank's constant
By substituting the given values;
