물질파. 142 g ball λ = 100. pm X-ray de Broglie

 

 

How fast must a 142 g baseball travel in order to have a de Broglie wavelength that is equal to that of an X-ray photon with λ = 100. pm?

 

---------------------------------------------------

 

λ = h / mc

( 참고 https://ywpop.tistory.com/3539 )

 

 

 

c = h / mλ

= (6.626×10^(-34) kgm^2/s) / [(0.142 kg) (100. pm) (1 m / 10^12 pm)]

= (6.626×10^(-34)) / [(0.142) (100.) (1 / 10^12)]

= 4.67×10^(-23) m/s
