Snell's Law


The Snell's Law calculator allows you to find any of the four unknowns involved in the formula for calculating the angle of refraction of light passing from one medium to another with a different refractive index.

All you have to do is select one of the following variables in the calculator in the Snell's Law:

  • n1: refractive index of first medium
  • n2: refractive index of the second medium
  • Angle of incidence (written in degrees)
  • Angle of refracted beam (also in degrees)

When you have selected the variable, fill in the values of the rest of the unknowns and press the calculate button to get the result. If you have the angles of incidence or refraction in radians, here you can to grades

Hooke's Law

Hooke's Law

The Hooke's Law is used in physics to calculate the elongation of an elastic material (a spring, for example) from the force we apply and the constant of elasticity of the material on which we apply the force.

With the calculator below, you will be able to calculate any of the three variables involved in the mathematical formula for solving Hooke's Law. Just select the one you want to calculate, fill in the corresponding data and click on the calculate button to get the result.

Weight calculator for other planets

Calculate weight on other planets

If you want to know your weight on other planetsOur online calculator will let you know what you would weigh on Mars, Jupiter or even on the Moon. To do this you only have to enter what you weigh here on Earth and click on the calculate button, so you will automatically know how the gravity of each of the planets influences on your mass and remember, weight and mass are not the same magnitudes since the weight varies according to gravity.

For example, if a child weighs 30 kilograms on Earth, on Mercury it would weigh only 11.7 kilograms. Surprising, isn't it? Find out how much you weigh on other planets:
