Calculate the wavelength of 100 kg rocket moving with a velocity of 300 km per hour.

Answer

`7.95xx10^(-38)m`

Explanation

According to de Broglie equation,
`lambda=(h)/(mv) , h=6.626xx10^(-34)"kg" m^(2)s^(-1) , m=100 "kg"`,
`v=300 "km"hr^(-1)=(300xx1000)/(60xx60)ms^(-1)=83.33 ms^(-1)`
` lambda=((6.626xx10^(-34) "kg"m^(2)s^(-1)))/((100"kg")xx(83.33ms^(-1)))=7.95xx10^(-38) m`.
