If the threshold frequency for tungsten is 1 3 ... - JAMB Physics 2011 Question
If the threshold frequency for tungsten is 1.3 x 1015Hz, what is its work function?
[H = 6.6 x 10-34 Js]
[H = 6.6 x 10-34 Js]
A
8.58 x 10-19 J
B
8.50 x 10-15 J
C
8.58 x 10-17 J
D
8.85 x 10-18
correct option: a
Work function, w = hfo 6.6 x 10-34 x 1.3 x 1015
= 8.58 x 10-19
= 8.58 x 10-19
