calculate the wavelengths of the following: A) a muon (a subatomic particle with a mass of 1.884x10^-25g) traveling at 2.30x10^2 m/s B) an electron (m=9.10939x10^-28g) moving at 3.80x10^6 m/s in an electron microscope
A)
muon mass = 1.884x10^-25 g
= 1.884 x 10^-28 kg
velocity = 2.30x10^2 m/s
wave length (lamda) = h / mv
= 6.625 x 10^-34 / (1.884 x 10^-28 x 2.30x10^2)
= 1.53 x 10^-8 m
= 15.3 nm
B)
electron mass = 9.10939x10^-28 g
= 9.10939x10^-31 kg
velocity = 3.80x10^6 m/s
wave length (lamda) = h / mv
= 6.625 x 10^-34 / (9.10939x10^-31 x 3.80x10^6)
= 1.91 x 10^-10 m
