Snell's Law

Equation and meaning

\[( ( ( sin ( i ) ) ) / ( ( sin ( r ) ) ) ) = ( ( ( ( n_2 ) ) ) / ( ( ( n_1 ) ) ) )\]

Snell's Law Where : n2 is the Refrective Index of Medium 2,n1 is the Refrective Index of Medium 1,i is the Angle of Incidence,r is the Angle of Refrection,

Variables in this formula

i — I
Enter this value unless it is the selected unknown.
n_1 — N 1
Enter this value unless it is the selected unknown.
n_2 — N 2
Enter this value unless it is the selected unknown.
r — Radius
Radius SI unit: m
Equation 2

Equation and meaning

\[( ( ( sin ( i ) ) ) / ( ( sin ( r ) ) ) ) = ( ( ( ( v_1 ) ) ) / ( ( ( v_2 ) ) ) )\]

Snell's Law Where : n2 is the Refrective Index of Medium 2,n1 is the Refrective Index of Medium 1,i is the Angle of Incidence,r is the Angle of Refrection,

Variables in this formula

i — I
Enter this value unless it is the selected unknown.
r — Radius
Radius SI unit: m
v_1 — V 1
Enter this value unless it is the selected unknown.
v_2 — V 2

How to use this calculator

  1. Leave one value emptyThe empty field is automatically treated as the unknown.
  2. Enter known values and unitsChoose N, kgf, dyn, SI or another compatible unit when available.
  3. Review the automatic answerThe result appears immediately and is substituted back into the formula to check the residual.
