WebApr 3, 2024 · The speed of light in vacuum is a constant quantity. We can say that optical density is directly proportional to refractive index and inversely proportional to speed of light for that given medium. Complete Answer: Absolute refractive index is defined as the ratio of speed of light in vacuum to that in a given medium. It is represented as. 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. ttings earlsWebOptical density (OD) measurement of bacterial cultures is a common technique used in microbiology. Researchers have primarily relied on spectrophotometers to make these measurements, however the measurement is actually based on the amount of light scattered by the culture rather than the amount of light absorbed. t t in python
