Question:

What will be the de-Broglie wavelength of a proton moving with kinetic energy E (m = mass of proton, c = speed of light)?

Options:

h/\(\sqrt {2mE}\)

h/\(\sqrt {8mE}\)

hc/\(\sqrt {2mE}\)

h/\(\sqrt {2E}\)

Correct Answer:

h/\(\sqrt {2mE}\)

Explanation:

The de-Broglie wavelength is given by

\(\lambda \)=h/\(\sqrt {2mE}\)
