Question
The de Broglie wavelength of a neutron correspoding to root mean square speed at 927oC is λ. What will be the de Broglie wavelength of the neutron correspoding to root mean square speed at 27oC?
Options
A.λ/2
B.λ
C.2 λ
D.4 λ
Solution
K.E. of neutron E = 3/2 kT
λd =
⇒ λ2 = λ
= 2λ.
λd =
⇒ λ2 = λ
= 2λ.Create a free account to view solution
