# At what speed is an electron's de Broglie wavelength (a) , (b) , (c) , and (d) ?

(a)

(b)

(c)

(d)

See the step by step solution

## Part(a) Step 1: Given Information

The electron's de Broglie wave length is

## Part(a) Step 2: Calculation

We can start the solution with expression for de-Broglie wavelength

This speed is larger than speed of light, so we must calculate relativistic speed:

## Part(b) Step 1: Given Information

The electron's de Broglie wave length is

For we have:

## Part(c) Step 1: Given Information

The electron's de Broglie wave length is

For we have:

## Part(d) Step 1: Given Information

The electron's de Broglie wave length is

For we have:
