How to find the wavelength of a particle with mass?

AI Thread Summary
The discussion focuses on calculating the deBroglie wavelength of an electron with a specified speed of 2.2x10^6 m/s. The user correctly identifies the momentum formula, P=MV, and calculates the momentum as 2x10^-24 kg·m/s. They then apply the deBroglie wavelength formula, λ = h/p, resulting in a wavelength of approximately 3.33x10^-10 meters. The method used for the calculation is validated by other participants, confirming its accuracy. Overall, the approach to finding the wavelength of a particle with mass is deemed correct.

Homework Statement



Does the following question ask what my title says? I study pack says "How to find the wavelength of a particle with mass?" So, is the following question good?

Question: What is the deBroglie wavelength of an electrion with a speed of 2.2x10^6 m/s

Answer I got: First, calculate the momentum, P=MV
(9.11x10^-31)(2.2x10^6m/s) = 2x10^-24

So... Wavelength = h/p = 6.62x10^34/2x10^-24

= 3.33x10^-10

Is this correct guys? Thanks!

The method is good - I assume you calculated correctly at each step. That answer is certainly a typical size.
 

Thread 'Errors and significant figures'

I multiplied the values first without the error limit. Got 19.38. rounded it off to 2 significant figures since the given data has 2 significant figures. So = 19. For error I used the above formula. It comes out about 1.48. Now my question is. Should I write the answer as 19±1.5 (rounding 1.48 to 2 significant figures) OR should I write it as 19±1. So in short, should the error have same number of significant figures as the mean value or should it have the same number of decimal places as...

Thread 'A cylinder connected to a hanging mass'

Thread 'A cylinder connected to a hanging mass'

Let's declare that for the cylinder, mass = M = 10 kg Radius = R = 4 m For the wall and the floor, Friction coeff = ##\mu## = 0.5 For the hanging mass, mass = m = 11 kg First, we divide the force according to their respective plane (x and y thing, correct me if I'm wrong) and according to which, cylinder or the hanging mass, they're working on. Force on the hanging mass $$mg - T = ma$$ Force(Cylinder) on y $$N_f + f_w - Mg = 0$$ Force(Cylinder) on x $$T + f_f - N_w = Ma$$ There's also...
