2. Results and discussion

The principle motivation behind this analysis is to look at the marvels of reflection and refraction of light, and to confirm the laws of reflection and refraction. The law of reflection demonstrates that the edge of frequency is equivalent to the point of refraction. After I found the estimations on the above table, I calculated the last segment utilizing the formula:

The basic edge of all out inward refection is the edge at which light going through a medium turns out to be totally reflected. At the point when the edge of occurrence is more noteworthy than the basic edge, light doesn't adhere to Snell's Law. Rather than refracting, the beam of light reflects. Aside from this distinction in refraction, Snell's Laws is followed all through.

3. Questions

If a laser with different wavelengths is used, which one will be different, angle of reflection or angle of refraction? Explain the reason.

The point of reflection is equivalent to edge of rate. The edge of rate is edge between beam (laser) and the line opposite to the surface. Changes in wavelength does not affect it. However, from n = c/v , v=f*λ you can find n = c/(f*λ). Refractive file and frequency are contrarily corresponding.
