Calculate the de Broglie wavelength of: a) A person running across the room (assume 180 kg at 1 m/s) b) A 5.0 MeV proton

a

b

Explanation:

From the question we are told that

   The mass of the person is  

    The speed of the person is  

    The energy of the proton is  

Generally the de Broglie wavelength is mathematically represented as

Here  h is the Planck constant with the value

So  

=>

Generally the energy of the proton is mathematically represented as

Here  is the mass of proton with value  

=>    

=>  

=>  

So

so    

=>    

c because the news are a source of information of things that happen on the daily and shows evidence about that particular topic
