Derivation of de broglie wavelength eqution - Physical Electronics

This chemistry video tutorial explains how to calculate the de broglie wavelength of large objects and small particles such as electrons. It contains plenty of examples and practice problems.

It's a shame that this wrong derivation is done in so many high school level books, and millions of kids every year learn a wrong thing.
deBroglie wouldn't deserve a Nobel if he simply did this! Reading his famous PhD thesis paper clears everything up.

deBroglie's relation was a hypothesis. How can someone derive a "hypothesis" from earlier theories?

If deBroglie's equation inherently contained E=mc^2, it would mean Schroedinger's equation is relativistic and there would be no need of relativistic QM!

c cannot be replaced with v, c is the speed of light and v is the velocity of particle ... this is wrong explaination. Debroglie's hypothesis is for material waves, and for material waves c is not equal to v, only photon travels with the velocity of light i.e. 'c', but here we are talking about material waves.

How would you replace c to v.
C is the speed of light and V is the velocity of particle.
Your explanation is wrong

Superb explanations... very easy to understand...

This video clear my confusion regards derivation. Thanks
