Answer 2

Snell's law in the direction of the refracted ray separating to media

• Snell's law, additionally referred to as the law of refraction, may be a law stating the connection between the angles of incidence and refraction, once relating light-weight passing from one medium to a different medium like air to water, glass to air, etc.
• Snell's Law states that the quantitative relation of sine  of angle of incidence and sine of angle of refraction is usually constant for a given combine of media.
• Where n may be a constant that is that the index of refraction
• Let us think about that light-weight enters from medium one to medium two = λ1/λ2
• Here, vn is that the rate of sunshine in several medium and
• λn is  velocity of light in respective medium
• You may be inquisitive however we have a tendency to obtained the expression in blue color, we have a tendency if we outline it in a straightforward approach, the fundamental reason for refraction is because of the amendment in rate of sunshine by coming into a medium of various index of refraction.
• So, if a medium has less index of refraction, then the rate of the velocity of light in that medium would be more but if a medium has more refractive index then the velocity of light in that medium would be comparatively less.
• v is directly proportional  to 1/n = v1/v2 =n2/n1 = n21

Therefore, Snell's law is proved
