Well, it wasn't invented, but it was first measured by Ernst Abbe.

Why can the refracted ray can also be the incident ray?

The refracted ray can coincide with the incident ray when light moves from one medium to another at a 90-degree angle relative to the boundary between the two media. This scenario leads to no bending of the light ray, resulting in the refracted ray following the same path as the incident ray.


Does the refracted ray bend towards the normal in water or vegetbale oil?

In water, the refracted ray will bend towards the normal, while in vegetable oil, the refracted ray will also bend towards the normal, but to a greater degree compared to water.


What is the angle between refracted ray and the normal?

The angle between the refracted ray and the normal is called the angle of refraction. It is measured from the normal to the refracted ray inside a medium due to the bending of light as it passes through different mediums.


How do the direction of the original incident ray and second refracted ray compare?

The direction of the original incident ray and the second refracted ray are typically different, as the second ray is refracted in a different manner from the first ray. This is due to the change in speed and angle as light passes through different mediums, causing the rays to bend at different angles.


The angle of refraction is measured between the refracted ray and what other line?

The angle of refraction is measured between the refracted ray and the normal line (perpendicular line) to the surface of the material at the point of incidence.

What is a 'refracted ray'?

It splits in differents colors according to their different wave length. An example of refracted light is a rainbow. The ray is split in 7 colors: red, orange, yellow, green, blue, indigo and violet.
