Question

The work function (Wo) of some metals is listed below. Which metals will show
photoelectric effect when light of 300 nm wavelength falls on the metal?
Metal. Li Na K Mg Cu Ag Fe Pt W
Wo (eV) 2.4 2.3 2.2 3.7 4.8 4.3 4.7 6.3 4.75


PLEASE ANSWER AS SOON SA POSSIBLE ​

Answer 1

Answer:

I thing question is uncomplete soory question is uncomplete than who to answer you

Answer 2

Answer:

K.E = E - ¢

calculate E = 1240/Lemda

E = 4.134

we know that , K.E can never be negative quantity..

check all options by putting work function of metal ,if Ke is -ve ,that metal of wo wll not show photoelectric effect

4.3,4.8,4.7,6.3,4.75 work function ll not show photoelectric effect

if it is correct

mark it as brainlist
