g A particle is trapped in a 20 nm wide infinite potential well. What is the wavelength of the particle corresponding to n
malfutka [58]

Question:

A particle is trapped in a 20 nm wide infinite potential well. What is the wavelength of the particle corresponding to n = 7 in nm?

Answer:

<em></em>\lambda_n = 5.71\ nm<em></em>

<em></em>

Explanation:

Given

L = 20nm --- the width

n = 7

Required

Determine the wavelength (\lambda)

This is calculated as:

\lambda_n = \frac{2L}{n}

Substitute values for L and n

\lambda_n = \frac{2*20nm}{7}

\lambda_n = \frac{40nm}{7}

\lambda_n = \frac{40}{7}nm

\lambda_n = 5.71428571\ nm

<em></em>\lambda_n = 5.71\ nm<em> --- approximated to 3 significant figures</em>
