І. 서론
As we discussed in last report, light actually acts like wave in certain circumstances. Reflection, refraction, diffraction…… Though wave-like properties had been examined, some critical experiments were enough to confuse scientists between wave and particle. Until scientists finally realize that there would be no more problems only if we do not particle to exist in a single point. After the enlightenment, people were compelled to recognize that matters, which we thought would exist in points, are actually distributed in area.

In the Fabry-Pérot interferometer experiment, we have some disturbance between 0.25m to 0.30m. The interval between the peaks suddenly becomes short. When we tried another experiment, we confirmed that Figure 1 had some error (Looking at Figure 3).
We think the reason of the error is caused by the process of experiment. During we were performing the experiment; we moved the mirror by hand. The hand was affected to motion sensor and the error occurred.
Therefore, we could conclude that;
First, by using partial reflectors, we can make the Fabry-Pérot interferometer. By using this interferometer, we could calculate the wavelength.
Second, by using diffraction grating composed of metal bars, we can make the bragg diffraction experiment, and we could calculate the wavelength from it.
Third, from last three experiments, we could confirm that electromagnetic wave really have the properties of wave.
