The work function for Al, K and is 4.28 ...

The work function for Al, K and is 4.28 eV, 2.30 eV and 5.65 eV respectively. Their respective threshold frequencies would be

A

`PtgtAlgtK`

B

`AlgtPtgtK`

C

`KgtAlgtPt`

D

`AlgtKgtPt`

Text Solution

Verified by Experts

The correct Answer is:
A
(a) : Work function, `phi_(0)=hv_(0)`
where `v_(0)` is the threshold frequency. So, `phi_(0)propv_(0)`
Hence `PtgtAlgtK`
