Question 19: NCERT Solutions for 12th Class Physics: Chapter 11-Dual Nature of Radiation and Matter
What is the de Broglie wavelength of a nitrogen molecule in air at 300 K? Assume that the molecule is moving with the root-mean-square speed of molecules at this temperature. (Atomic mass of nitrogen = 14.0076 u, K = t. 38 × 10-23 J K-1).
Solution:
Let us first calculate mass of each N2 molecule.
