Calculating Threshold Frequency of a Metal Substance
Work Function
The work function is the amount of energy required to remove an electron from a metal surface. In this case, the work function of the metallic substance is given as 5 eV.
Threshold Frequency
The threshold frequency is the minimum frequency of light required to eject an electron from the surface of a metal. It is given by the equation:
where f0 is the threshold frequency, W0 is the work function, and h is Planck's constant.
Calculating Threshold Frequency
Substituting the given values in the above equation, we get:
f0 = (5 eV)/(4.14 x 10-15 eV s)
Simplifying the expression, we get:
Therefore, the threshold frequency of the metallic substance is approximately 1.21 x 1015 Hz.

Threshold Frequency
The threshold frequency is the minimum frequency of light required to eject an electron from the surface of a metal. It is given by the equation:
f0 = (W0/h)
where f0 is the threshold frequency, W0 is the work function, and h is Planck's constant.
Calculating Threshold Frequency
Substituting the given values in the above equation, we get:
f0 = (5 eV)/(4.14 x 10-15 eV s)
Simplifying the expression, we get:
f0 = 1.21 x 1015 Hz
Therefore, the threshold frequency of the metallic substance is approximately 1.21 x 1015 Hz.

Threshold frequency ( Vo) = Work function (Φ) / plancks constant (h).
=> Vo = 5 ev / 6.6 x 10^−34.
=> = 1.2 x 10^15 Hz.
=> Vo = 5 ev / 6.6 x 10^−34.
=> = 1.2 x 10^15 Hz.
