Question

1. Calculate the wavelength associated with earth, a piece of
stone and electron with the help of de Broglie equation.
Their masses and velocities are as given below:
Mass of earth = 6 x 1024 kg
Mass of piece of stone = 0.1 kg
Mass of electron = 9.1 x 10-31 kg
Velocity of the axial movement of earth = 3 x 104 ms -1
Velociy of piece of stone = 1.0 ms -1
Velociy of electron = 1.2 x 105 ms 1
h = 6.626 x 10-34 Js
Out of these, which system has a measurable wavelength ?​

Answer 1

Answer:

Answer:

3.68 x 10^-65

Explanation:

De Broglie wavelength is calculated as  

λ=  h  / mv

λ =  6.62 x 10^-34 /   6 x 10 ^24 x 3 x 10 ^6

λ=  3.68 x 10^-65
