SNELL'S LAW. What is the first statement of the video clip?
Willebrord Snell was born in 1580 in Leiden. He began to study mathematics at a very
young age.
He entered the university of LeIden and initially studied law, but soon he turned his attention towards mathematics and started teaching at the
university by the time he was just 20
In the year of 1613 snell succeeded his
father as professor of mathematics.
He did some important work in mathematics including the method of calculating the approximate value of pi
by a polygon. His method of using 96-sided polygon gives the correct value
of pi
up to seven places while the classical
method only gave this value
up to two correct places
SNELL'S LAW. What is the Second statement of the video clip?
Snell also
published some books including his work
on comets.
However his biggest contribution to
science was his discovery
of the laws of refraction.

undeviated straight line
until it encounters a change of medium
At such a change, a portion of the incident light passes
into the second medium in a different direction.
