Wavelength of bullet and proton, same momentum

AI Thread Summary
A question was raised about the wavelengths of a bullet and a proton that have the same momentum. The de Broglie wavelength formula, which states that wavelength equals Planck's constant divided by momentum, was referenced. Since both the bullet and proton share the same momentum, they consequently have the same wavelength. The discussion confirmed that the wavelengths are indeed equal. This highlights the application of de Broglie's principle in understanding wave-particle duality.

Hi.

There's this question that was posed.
And I'm totally lost.:redface: If my professor explained how it's all derived it would've been useful.
Here we are:

A bullet and a proton have the same momentum. Which has the longer wavelength?

Any help?
Thanks,

Tell me what you know about the de Broglie wavelength.
 
Ahh.. de Broglie's.. wavelength = h / momentum..
Because h is Planck's constant.. and momentum is constant in this example.
wavelength is constant.. So they both have the same wavelength.

Thanks.

Thanks.
Glad to be of service :smile:
 

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 'Collision of a bullet on a rod-string system: query'

Thread 'Collision of a bullet on a rod-string system: query'

In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...

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...
