Who's formulated the Snell's law

Answer 1

it states that the ratio of sine of angle of incidence/sine of angle of refraction=constant, for the light of given color and given pair of medium.

where n1 and n2 are the indices of refraction of light in different materials.

Answer 2

Snell's law is defined by the relation n1 * sin(a1) = n2 * sin(a2) where n is the index of refraction of the material and a is the angle. Different mediums have different indices of refraction and therefore bend light at different angles.

Answer 3

Snell's law was formulated and named after astronomer Willebrord Snellius. That said, the scientist Ibn Sahl was the first to accurately describe the law.

Answer 4

the ratio of the incident angle to the sine of the rafracted angle is constant

Answer 5

Snell's law was discovered by Thomas Harriot in 1602.
