WebWhen you enter a denser medium, speed of light ray slows down and hence the refracted ray bends towards the normal. When you enter a less dense medium, speed of light ray increases and hence the refracted ray will bend away from the normal. WebThe moisture content of honey (or conversely the soluble solids content) is determined by measuring the refractive index of honey using a refractometer. The refractometer measures the amount of refraction (or distortion) as light passes through a honey sample. The amount of refraction shows how much solid and fluid is present. reddish start well hub
