Energy to Wavelength Calculator

Calculate Wavelength from Energy

Formula

The formula to calculate the wavelength (λ) from energy (E) is:

\[ \lambda = \frac{h \cdot c}{E} \]

What is Energy to Wavelength?

Energy to wavelength is defined as the conversion of the total energy contained within a photon into the wavelength.

Example Calculations

Example 1:

Using the formula:

\[ \lambda = \frac{6.6261 \times 10^{-34} \cdot 299792458}{3.0 \times 10^{-19}} \approx 6.6261 \times 10^{-7} \text{ m} \]

Example 2:

Using the formula:

\[ \lambda = \frac{6.6261 \times 10^{-34} \cdot 299792458}{5.0 \times 10^{-19}} \approx 3.973 \times 10^{-7} \text{ m} \]
