Snell's Law
The principle governing the refraction of light, stating that n1 * sin(θ1) = n2 * sin(θ2).
2
New cards
Index of Refraction
A measure of how much the speed of light is reduced in a medium compared to its speed in a vacuum.
3
New cards
Velocity of Light in Medium 1
The speed at which light travels in medium 1, calculated using v1 = c/n1.
4
New cards
Velocity of Light in Medium 2
The speed at which light travels in medium 2, calculated using v2 = c/n2.
5
New cards
Velocity of Light in Water
The speed at which light travels in water, calculated using vw = c/n.
6
New cards
Calculate n2
n2 = n1 * (sin(θ1) / sin(θ2)) uses Snell's Law to find the index of refraction of the second medium.
7
New cards
Calculate Speed of Light
Speed of light in a medium is given by the formula v = c/n, where c is the speed of light in a vacuum.
8
New cards
c (Speed of Light)
The speed of light in a vacuum, approximately 3.00 x 10^8 m/s.
