[@Mr_nilesh05]

1:30:07 answer ❤
To determine if the photon can emit an electron from the metal surface, we need to compare the energy of the photon (E) to the work function (Φ) of the metal.
First, let's calculate the energy of the photon:
E = hc / λ
where:
E = energy of the photon
h = Planck's constant (6.626 × 10^-34 J s)
c = speed of light (3 × 10^8 m/s)
λ = wavelength of the photon (5000 Å = 5 × 10^-7 m)
Plugging in the values:
E = (6.626 × 10^-34 J s) × (3 × 10^8 m/s) / (5 × 10^-7 m)
E ≈ 3.98 × 10^-19 J
Now, let's convert the energy from joules to electronvolts (eV):
1 eV = 1.602 × 10^-19 J
So:
E ≈ 3.98 × 10^-19 J / (1.602 × 10^-19 J/eV) ≈ 2.49 eV
Now, comparing the energy of the photon (2.49 eV) to the work function (2.6 eV), we can see that:
E < Φ
The energy of the photon is less than the work function of the metal. Therefore, the photon will not be able to emit an electron from the metal surface.

1:19:06 sec Ans. (K1-W)/2 = K2

[@prosadecora]

1:19:12
K2 = K1/2- W/2 ❌
Here's the correct derivation:
Given:
* Initial frequency of radiation = f
* Final frequency of radiation = f/2 (frequency is halved)
Einstein's Photoelectric Equation:
* hν = KE + W
where:
* h = Planck's constant
* ν = frequency of radiation
* KE = kinetic energy of the ejected electron
* W = work function of the metal (minimum energy required to eject an electron)
Initial Condition (Frequency = f):
* hν = KE₁ + W
Final Condition (Frequency = f/2):
* h(f/2) = KE₂ + W
Subtracting the Final Condition from the Initial Condition:
* hν - h(f/2) = KE₁ - KE₂
Simplifying:
* hν/2 = KE₁ - KE₂
Rearranging:
* KE₂ = KE₁ - hν/2
Conclusion:
When the frequency of radiation is halved, the kinetic energy of the electron decreases by hν/2.
Note: The work function (W) remains constant for a given metal.

ik no one will give a fck abt my statement...

In laws of photoelectric effect.
There is this statement that there is no time lag between incident radiation and electron emission..
IDK but the smallest unit of time Is Planck time... 10 power inverse -43...
And it's not possible that there is no time lag between them... And if there is... Then this would cease to exist. It will not exist.. Believe me.
It cannot happen that there is no time lag... There have to be some time lag between the process.

Q. If Frequency of radiation is half then what will be effect on K.E of Electron??
Ans : It will be More than Half
K2 =( K1 + W)/2
Here since K1 is halfed but we add half of work function in it. So , The K.E become more than Half..
Sir if its correct please Pin my comment
