Whatwill be thewavelengthof a ballof mass0.1 kgmovingwitha velocityof 10 ms^(-1)

Answer»

SOLUTION :According to thede Broglieequation
`LAMBDA=(h)/( mv) `
`lambda =(6.626 xx 10^(34) js)/((0.1 kg10 ms^(-1))`
where m= 0.1 kg
v=10 `ms^(-1)`
`h= 6.626xx 10^(34) Js`
`=6.626 xx 10^(34) kg ^(-1) m^(-1) s^(2)` but`J= kg m^(2) s^(2)`
`=6.626 xx 10^(34) m`
