Calculate Photoelectric Effect Energy

Formula

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

\[ E = h \cdot v \]

Where:

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:

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.
