Find de Broglie wavelength of wave associated with a particle of rest mass `5 xx 10^(-30) kg` and moving with a speed `1.8 xx 10^8 m s^(-1) (h=6.6 xx 10^(-34) Js)`.

Explanation

de -Broglie wavelength `=lamda`=?
`m=9 xx 10^(-31) kg`
`v= 1.5 xx 10^(8) ms^(-1)`
`h= 6.6 xx 10^(-34) Js`
`lmada= (h)/(mv)`
`lamda= (6.6 xx 10^(-34))/(9 xx 10^(-31) xx 1.5 xx 10^(8))`
`lamda= 0.489 xx 10^(-11)`
`lamda= 4.89 xx 10^(-12)m`
