photoelectric effect
can the metals be also different here? or only the energy of light (frequency) is different but the metal is same?

Note for OP
+solved @user1 @user2... to close the thread when your doubt is solved. Mention the users who helped you solve the doubt. This will be added to their stats.different Vs is needed bcuz their Kinetic energy max are different, which is hv-Φ, so different metals have different Φ which means their KEmax can be different even with the light's v being different or same, hence different metals can have different Vs
if the metals are same, then KEmax are different only bcuz of the light v are different, so they can also have different Vs
so that means both are valid?
so if frequency of incident radiation is the same, then different metals
depends on what is constant and what changes :)
i see, thanks
you have written that the frequencies are different so it must be the same metal
so if Vs is different, then
freq dif - metal same
freq same - metal dif
yeah it's clear now
