Photoelectric Effect Calculator

Formula

The formula to calculate the Photoelectric Effect Energy (E) is:

$E = h \cdot v$

Where:

$E$ is the Photoelectric Effect Energy (joules).
$h$ is Planck's constant (6.626 x 10^-34 J-s).
$v$ is the Frequency (Hz).

What is the Photoelectric Effect?

The photoelectric effect is a quantum phenomenon where electrons are emitted from the surface of a material when it is exposed to light of sufficient frequency. This effect was explained by Albert Einstein in 1905 and is a fundamental concept in quantum physics.

Example Calculation

Consider an example where:

Frequency (v): 5 x 10^14 Hz

Using the formula to calculate the Photoelectric Effect Energy:

$E = 6.626 \times 10^{-34} \cdot 5 \times 10^{14} = 3.31 \times 10^{-19} \text{ J}$

This means that the photoelectric effect energy for this example is approximately 3.31 x 10^-19 joules.
