    For the ones curious, I leave here a explanation of why refraction happens:
    (It can be explained as a consequence of 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 light bending is just a consequence of the conservation of momentum of photons!

    there is a mistake as shown in the video the speed of the light decline to 200,000km per secs but while calculating the refractive index of glass the have taken the speed as 225.000 km per secs
