Web2 Answers. Refraction is proportional to the angle away from the normal (away from right angles to the surface). In this case the angle is zero (the light enters perpendicular to the surface) so there is no refraction. Well, your light ray must have hit the curve at an exact point where the angle of incidence was zero, (the light ray was ...

WebMar 23, 2024 · refraction, in physics, the change in direction of a wave passing from one medium to another caused by its change in speed. For example, waves travel faster in … WebAtmospheric refraction is the deviation of light or other electromagnetic wave from a straight line as it passes through the atmosphere due to the variation in air density as a function of height. [1] This refraction is due to the velocity of light through air decreasing (the refractive index increases) with increased density.

WebThe refractive index of a glass is a function of the wavelength of light, a property known as dispersion. A plot of refractive index vs. wavelength is called a dispersion curve. Different glasses exhibit different dispersion curves, as shown below. In this experiment, you will measure the dispersion curve of a dense flint optical glass.
