It proposes that things we name particles, such as electrons, mix particle and wave characteristics in some way. This is quantum mechanics well-known wave-particle duality.

Because the intensity of the light fringes drops slowly as the order of the fringes increases, and the fringes are evenly spaced, the given graph displays a pattern of double-slit experiment.

In the double slit experiment, the position of the brilliant fringes can be written as follows:

$y_m=\frac{m位L}{d}$

As a result, the distance between any two brilliant fringes is

$$\begin{gathered} 螖y=y_{m+1}-y_m \\ =\frac{(m+1)位L}{d}-\frac{m位L}{d} \\ =\frac{位L}{d} \end{gathered}$$

We may calculate the ratio by rearranging this equation.

$d=\frac{位L}{螖y}$

The spacing in between two consecutive brilliant fringes is$1$cm, as seen in the diagram. hence

$d=\frac{\left(620脳{10}^{-9}\mathrm{m}\right)脳2.5\mathrm{m}}{1脳{10}^{-2}\mathrm{m}}$

$d=1.55脳{10}^{-4}\mathrm{m}$
