SUMMARY

The discussion focuses on calculating the de Broglie wavelength of a bullet with a mass of 41g traveling at 960m/s. The correct formula for the de Broglie wavelength is λ = h/mv, where h is Planck's constant, m is the mass, and v is the velocity. The negligible diffraction effects of the bullet are attributed to its extremely small wavelength, which is not observable in practical scenarios. A common mistake noted was the confusion between the de Broglie wavelength and the Compton wavelength, which is calculated using the formula h/mc.

PREREQUISITES
  • Understanding of de Broglie wavelength and its formula λ = h/mv
  • Familiarity with Planck's constant (h)
  • Basic knowledge of mass and velocity in physics
  • Awareness of diffraction effects in wave phenomena
NEXT STEPS
  • Research the implications of de Broglie wavelength in quantum mechanics
  • Learn about the differences between de Broglie wavelength and Compton wavelength
  • Explore practical applications of wave-particle duality in everyday objects
  • Investigate the conditions under which diffraction effects become significant
USEFUL FOR

Students studying quantum mechanics, physics educators, and anyone interested in the wave-particle duality of matter.

This question appeared in my exam .

Q. A bullet of mass 41g travels at 960m/s. what wavelength can we associate with it?
why does the wave nature of the bullet not reveal itself though diffraction effects?

Ans..

i find de broglie wave length by formula

lamda = h/mc

but didnt able to give answer of the WHY question?

somebody help what does it mean?
 
Physics news on Phys.org
Why? Just because the wavelength is so small that diffraction effects are negligible. By the way, you've got the two wavelengths confused. h/mc is the Compton wavelength. The be Broglie wavelength is h/mv.
 
thanks bill k..
yes i put the h/mv..

but written wrong reason there..
