A particle A moving with a certain veloc...

A particle A moving with a certain velocity has a de Broglie wavelength of 1 A. If particle B has mass 25% of that A and velocity 75% of that of A, the de Broglie wavelength of B will be approximately

A

`1Å`

B

`5.3Å`

C

`3Å`

D

`0.2Å`

Text Solution

Verified by Experts

`lamda_(A)=h/(mv),lamda_(B)=h/(0.25mxx0.75v)`
`(lamda_(B))/(lamda_(A))=1/(0.25xx0.75)=5.3`
`thereforelamda_(B)=5.3lamda_A=5.3Å`

According to Louis de Broglie, a French physicist, every moving material particle has a dual nature i.e., wave and particle nature. The two characters are co-related by de Broglie relation lambda=(h)/(m upsilon(p)). Here lambda represents wave nature while p or m upsilon accounts for the particle nature. Since h is constant , the two characters are inversely proportional to each other. This relationship or equation is valid mainly for microscopic particles such as electrons, protons, atoms, ions, molecules etc. It does not apply to semi-micro or micro particles.
