Atoms And Nuclei

The P.E. 'U' of a moving particle of mass 'm' varies with 'x'-axis as shown in figure. The deBroglie wavelength or the particle in the regions \(0 \leq x \leq 1\) and \(x > 1\) are \(\lambda_1\) and \(\lambda_2\) respectively. II the total energy of the particle is '\(\mathrm{nE}\)', then the ratio \(\lambda_1 / \lambda_2\) is
