Question

If the velocity of the particle is reduced by a factor of two, by what factor does the de Broglie wavelength change?

2

4

1/2

1/4

Answer 1

2

Answer 2

\[\lambda=h/mv\] where lambda is the de broglie wavelength..v is the velocity..
they have given its reduced by a factor of 2..so denominator is reduced by 2..
so \[\lambda=h/(mv/2)\]

Answer 3

so what will the answer be?
