The wavelength of electron waves in two orbits `(lambda_(1) : lambda_(2))`

A

`25 : 9`

B

`5 : 3`

C

`9 : 25`

D

`3 : 5`

Text Solution

Verified by Experts

The correct Answer is:
A
`lambda=(h)/(sqrt(2mKE)), (lambda_(1))/(lambda_(2))=sqrt((KE_(2))/(KE_(1))), (3)/(5)=sqrt((KE_(2))/(KE_(1))),(KE_(1))/(KE_(2))=(25)/(9)`
