Question

The difference in refraction angles is small and difficult to detect in this simulation, so i have shown apossible experimental setup for you to try. how much does the angle of refraction change from 380nm to700nm when the incident angle is 80?

Answer 1

The change in the angle of refraction from 380nm to 700nm at an 80-degree incident angle is due to dispersion and can be calculated using Snell's Law with known refractive indices.

Step-by-step explanation:

The angle of refraction changes for different wavelengths of light due to the phenomenon of dispersion, where light separates into its constituent colors upon passing through a medium. This separation occurs because different wavelengths of light have different refractive indices.

When light enters a medium at an incident angle other than 90 degrees, each wavelength is refracted at a different angle. Specifically, shorter wavelengths (like violet) are refracted more than longer wavelengths (like red). The actual change in the angle of refraction from 380 nm to 700 nm when the incident angle is 80 degrees depends on the indices of refraction of the materials the light is passing through and from.

Using Snell's Law, one could calculate the specific refraction angles for these wavelengths if the refractive indices are known.
