The de-Broglie wavelength of neutron in thermal equilibrium at temperature T is
Options
(a) 30.8 / √T Å
(b) 3.08 / √T Å
(c) 0.308 / √T Å
(d) 0.0308 / √T Å
Correct Answer:
30.8 / √T Å
Explanation:
From formula
= h / √ 2mKT
= 6.63 x 10⁻³⁴ / √ (2 x 1.67 x 10⁻²⁷ x 1.38 x 10⁻²³ T) . m
[ By placing value of h, m and k ]
= 30.8 / √T Å
