What Happens to the de Broglie Wavelength as Mass Approaches Infinity?

AI Thread Summary
As mass approaches infinity in the de Broglie wavelength formula, the wavelength approaches zero, suggesting that massive particles behave more like point particles. This implies that larger mass particles do not exhibit significant wave-like properties, allowing for the application of classical Newtonian physics. The de Broglie wavelength equation indicates that all particles theoretically exist as waves, but practical observations show that high-mass objects, like a cricket ball, do not demonstrate these wave characteristics. Thus, the discussion highlights the transition from quantum to classical behavior as mass increases. Ultimately, the relationship between mass and wave-like properties is crucial in understanding the limits of quantum mechanics in classical physics.

If, in the expression for the de Broglie wavelength, we let m -> infinity, do we get the classical result for matter?

de Broglie wavelength = h/mv

so as m goes to infinity the de Broglie wavelength goes to 0. So does this mean that particles with larger mass don't display wavelike properties and therefore can be treated as a point particle which means we can apply classical Newtonian physics?

The de Broglie wavelength assumes that ALL particles exist as a wave with wavelength h/mv
 
Yeah I understand that but if their wavelength is small enough they don't display (a cricket ball doesn't display wave like properties) wave like properties?

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...
