Web7 apr. 2024 · Law 1 - The primary law of reflection expresses that the reflection point is dependably comparable to the point of incidence. If the episode beam falls on the plane mirror along with the typical, for example, 90°, the reflected beam will go along a similar way. Web7 apr. 2024 · Snell's law determines the angle of refraction at the interface of two materials. n 1 ⋅sin(θ) = n 2 ⋅sin(θ′) Where, n 1 and n 2 = Refractive indices of the two materials. θ = Incident angle of light. θ’ = The angle of refraction.
