At 200^(@)C, the velocity of hydrogen molecules is 2.4xx10^(5) cm/sec. In this case the de-Broglie wavelength is about

Answer»

`1Å`
`1000Å`
`100Å`
`10Å`

SOLUTION :Velocity of hydrogen `=2.4xx10^(5)`cm/sec
`=2.4xx10^(3)`m/sec
Mass of HYDROGE `=2/(60.2xx10^(23))`
`=3.32xx10^(-24)m-3.32xx10^(-27)kg`
`lamda=h/(mv)=(6.6xx10^(-34))/(3.32xx10^(-27)xx2.4xx10^(3))`
`=0.83xx10^(-10)m=1Å`
