Problem: How to calculate the de Broglie wavelength for each of the following? a. an electron with a velocity 10.% of the speed of light b. a tennis ball (55 g) served at 35 m/s (,80 mi/h)

FREE Expert Solution

We’re being asked to calculate the de Broglie wavelength for:


a. an electron with a velocity 10% of the speed of light 

b. a tennis ball (55 g) served at 35 m/s (,80 mi/h)


Recall that the de Broglie wavelength (λ) can be calculated using:


λ=hmv


where:

h = Planck's constant (6.626 × 10–34 kg • m2/s)

m = mass (in kg)

v = velocity (in m/s).
