Question

What is the speed of a proton having de Broglie wavelength of 0.08 Å​

Answer 1

Answer:

The de Broglie wavelength of a proton in a particle accelerator is 1.30×10−14 1.30 × 10 − 14 m.

Explanation:

Using that value under our square root sign for the energy, when we compute , we find that it's equal to 20 times 10 to the negative 15th meters. This value is also known as 20 femtometers. That's the de Broglie wavelength of a proton with this much kinetic energy.
