Problem

Neutrons in thermal equilibrium with matter at

27^{\circ}\text{C}

can be thought to behave like ideal gas. Assuming them to have a speed of

v_{ms}

, what is their De broglie wavelength

\lambda

(in nm). Fill

\left(\frac{156}{11}\right)\lambda

in the OMR sheet. [Take

m_n = 1.69 \times 10^{-27}

kg,

k = 1.44 \times 10^{-23}

J/K,

h = 6.60 \times 10^{-34}
