Question

Q.12 A material particle with a rest mass mo is moving with speed of light c. The associated de-Broglie wavelength is given by h m. B. h A.h/moc B.moc/h D.0 c. infinity


eplanation needed why not C A because the moving mass is not zero​

Answer 1

Answer:

Correct option is

B

Theory of special relativity, m′=γm=1−c2V2m

Debroglie wavelength, λ=m′vh=mvh1−c2V2

If v=c, then λ=0
