Optical density definition class 8

Weboptical density a spectrophotometric measurement of light scattered by a suspension at a particular wavelength. Optical density measurements can be used to determine the … WebBecause the light can't travel as quickly in the water as it does in the air, the light bends around the pencil, causing it to look bent in the water. Basically, the light refraction gives the pencil a slight magnifying effect, which makes the angle appear bigger than it actually is, causing the pencil to look crooked.
