Question

Voltage formula using wavelength and work function

Answer 1

Ohm's law equation (formula): V = I × R and the power law equation (formula): P = I × V. P = power, I or J = Latin: influare, international ampere, or intensity and R = resistance. V = voltage, electric potential difference Δ V or E = electromotive force (emf = voltage).

Answer 2

W=λ2hc−eVs1.

Given: wavelength and work function

To Find: Voltage formula

Solution:

It states the voltage across a conductor is directly proportional to the current flowing through it, provided all physical conditions and temperatures remain constant.

Ohm's law equation formula: V = I × R, where V is the voltage across the conductor, I is the current flowing through the conductor and R is the resistance provided by the conductor to the flow of current.

Since work function does not depend on the wavelength of incident light so it will be constant for both cases.

In order to convert a wavelength to energy in electronvolts (eV): Utilize Planck's energy equation E = h × c / λ.

Thus, W=λ2hc−eVs1.
