Calculate the wavelength associated with...

Calculate the wavelength associated with an electron (mass `9.1 xx 10^(-31)` kg) moving with a velocity of `10^3m sec^(-1) (h=6.626 xx 10^(-34) kg m^2 sec^(-1))` .

Text Solution

Verified by Experts

Here we are given
`m = 9.1 xx 10^(-31) kg `
` v= 10^3 m sec^(-1)`
`h = 6.626 xx 10^(-34) kg m^2 sec^(-1)`
`lamda =(h)/(mv) = (6.626 xx 10^(-34))/((9.1 xx 10^(-31) ) xx 10^3)`
`= 7.25 xx 10^(-7) m `
