The de-Broglie wavelength of a particle can be calculated using the formula:
λ = h / p
where λ is the de-Broglie wavelength, h is the Planck's constant (approximately 6.626 x 10^-34 J·s), and p is the momentum of the particle.
To find the momentum of particle A, we need to know its mass and velocity. The momentum of a particle can be calculated using the formula:
p = m * v
where p is the momentum, m is the mass of the particle, and v is the velocity of the particle.
Given that the de-Broglie wavelength of particle A is 1, we can substitute this into the equation for the de-Broglie wavelength:
1 = h / p
Now, let's solve for p:
p = h / 1
p = h
Therefore, the momentum of particle A is equal to the Planck's constant.
Note: The units of the Planck's constant are kg·m/s, so the momentum will have the same units.
