SUMMARY

Light traveling through different mediums, such as water and air, is governed by Snell's Law, which states that the ratio of the sines of the angles of incidence and refraction is equal to the ratio of the speeds of light in the respective mediums. Specifically, the equation is expressed as \(\frac{\sin \theta_1}{\sin \theta_2} = \frac{c_1}{c_2} = \frac{n_2}{n_1}\), where \(n_i\) represents the refractive index calculated as \(c / c_i\). This law is critical for understanding how light bends when transitioning between mediums with different refractive indices.

PREREQUISITES
  • Understanding of Snell's Law and its mathematical formulation
  • Knowledge of refractive indices of various mediums
  • Familiarity with the concept of angle of incidence and angle of refraction
  • Basic principles of wave optics
NEXT STEPS
  • Research the refractive indices of common materials, such as water and air

If light traveling in water hits an interface with air at angle x, what is the angle it will make when traveling in air?

what factors do i need to consider for this apart from:

different lights travel at different speeds

different mediums will affect angle of incidence

The thing you're looking for is probably called "Snell's law" (named after a Dutch scientist with the fancy Latin name Snellius):
[tex]\frac{\sin \theta_1}{\sin \theta_2} = \frac{c_1}{c_2} = \frac{n_2}{n_1}[/tex]
where [itex]n_i = c / c_i[/itex] and [itex]c_i[/itex] is the speed of light in medium i (and c in vacuum).
