Question

Estimate your de Broglie wavelength when you are running. (For this problem use h = 10^−34 in SI units and 1 lb is equivalent to 0.45 kg.) For the computation, estimate how fast you can run in meters per second.

A. your running speed ______ m/s

B. your mass ______kg

C. your de Broglie wavelength ______ m

Answer 1

A. your running speed 1.5 m/s

B. your mass 70 kg

C. your de Broglie wavelength
`6.32x10^(-36)`m

Step-by-step explanation:

Hello there!

In this case, since the equation for the calculation of the Broglie wavelength is:

`\lambda =(h)/(m*v)`

We can assume a running speed of about 1.5 m/s and a mass of 70 kg, so the resulting Broglie wavelength is:

`\lambda =(6.626x10^(-34)kg(m)/(s) )/(70kg*1.5(m)/(s) )\\\\\lambda =6.32x10^-36m`

Best regards!
