The light refraction can be used in the clinical significance in medicine especially in the optometry, the ophthalmology and the orthoptics, the refraction is also known as the refractometry which is used to determine the eye’s refractive error and the best corrective lenses to be prescribed.

@SimulatingPhysics 3 жыл бұрын

For the ones interested, here there is an explanation of refraction (very simple), using the conservation of momentum of photons: If in medium 1 the index of refraction is n1 and in medium 2 the index of refraction is n2 and for the definition of index of refractions and wavelength we have: n1 = c / v1 , v1 = λ1 * f n2 = c / v2 , v2 = λ2 * f Dividing the above equations we obtain: n2 / n1 = λ1 /λ2 So if n2 is higher than n1, the wavelength in medium 2 is smaller than in medium 1. Now because the photon momentum is: p = h / λ Applying the conservation of momentum of the incident and transmitted photon along the parallel line of medium separation: p1 = p2 → h/λ1 *sin(θ1) = h/λ2 *sin(θ2) → n1 *sin(θ1) = n2 *sin(θ2) This is the Snell Law!! So the refraction is just a consequence of the conservation of momentum of photons!

The answers are : 1) light always travel in wavefronts and wavefronts are parallel to each other, when incident ray enters the glass slab the speed light lights slows down and the wavefronts inside the water travels short distance whereas the wavefronts in air will travel more distance and when the wavefronts will completely get inside the water they will be bended and their speed will also get slow, but till the time they are inside water they will travel straight and when they will again come to rarer medium (air) the wavefronts in air will again travel more distance compared to the wavefronts in water and when they will completely get outside from water light speed will increase again and will continue to travel in a straight line.
