We know that every metal has some minimum threshold frequency value above which it can only emit the photo electrons.
00:21
It will only go through the photoelectric effect when some light falls in it.
00:26
The light must be of some frequency greater than this thresholds.
00:34
Frequency value.
00:36
Therefore the statement a is correct.
00:41
Now we know that the maximum kinetic energy of photo electrons is given by h nu minus 5.
00:51
Here 5 is the work function, work function of electron for your function of the metal which is a constant and h is the planks constant so k max is nothing but directly proportional to new.
01:05
And linearly proportional.
01:08
So k max is maximum kinetic energy of electron will linearly increase with the frequency of electrons, frequency of incident light falling on it, incident light.
01:22
Hence statement b is also correct.
01:27
Also we know that the intensity of light, more the intensity of light, more the number of photoelect.
01:38
More the number of photo electrons will be released.
01:45
So if i is more, number of photo electrons will be more...
