Can a stationary, massive particle have a de Broglie wavelength?

AI Thread Summary
A stationary, massive particle can technically have a de Broglie wavelength, but it is negligible due to the relationship defined by the de Broglie equation, where wavelength is inversely proportional to mass and velocity. In practice, no particle is completely stationary above absolute zero, as they exhibit some motion. For macroscopic bodies, a reference frame can always be found where they are in motion. Thus, while the concept holds mathematically, the practical implications render the de Broglie wavelength of massive particles extremely small. Understanding this relationship is essential in quantum mechanics.

Quick question
Can a stationary, massive particle have a de Broglie wavelength? I thougt not but there is a question that doesn't state a speed. I think it might be incorrect.

Cheers

There's no such thing as a stationary sub-atomic particle above absolute zero. For a macroscopic body you can always find a reference frame in which it is moving. But that does not answer your question ...

Hey Swain ... Yes Massive Particle have de Broglie wavelength...But it is very less to compare because According to de broglie Equation lambda=h/mv
wave length of the wave is invresely proportional to the mass... so when the masss of the particle increases its wavelength decreases comparitively
 

Thread 'Rolling without slipping on a curved surface'

Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...
