REFRACTIVE INDEX, WAVELENGTH OF A MEDIUM BY R.VELMURUGAN SHADOW EXPERIMENT

摘要

According to R.Velmurugan the relation between length of an object and it"s shadow length in air medium is L = L0 * Velmurugan constant in air / tanθ, the relation between length of an object and it"s shadow length in medium is L = L0 * Velmurugan constant in medium / tanθ, µ = tanθ1=1o in air / tanθ=1o in medium.
