It means that the speed of light in that medium is the same as in vacuum. This is ALMOST the case for stuff like "air". If you measure closely enough, it is only true for vacuum, all other materials have an optical density > 1.

What is the sine of angle of incidence divided by the sine of angle of refraction of equal optical density?
It is 1.
Volume to density 1ml water equals g?
1 gram (approx)
If 1 is equal to 10 then 100?
If you meant 'If 1 is equal to 10 then 100 equals to what?' then the answer is: 'any number'.
What is the density in grams per milliliter of a substance for which 1 pt equals 1 lb exactly?
Density = 1 lb/1 pt = 453.59 g/568.26 mL = 0.798 g/mL
2x plus 3 equals 4x2?
If you meant 2x+3=4x²x=(1±√(13))/4x1≈1.151387818866x2≈-0.651387818866
What does optical density of 1 means?
An optical density of 1 indicates that 90% of light is absorbed by the material being measured. It is commonly used in spectrophotometry to quantify the amount of light absorbed by a sample. A higher optical density value indicates greater light absorption.
1 optical density equals how many bacterial cells?
The relationship between optical density and bacterial cell count can vary depending on the species, growth phase, and experimental conditions. Therefore, it is not possible to directly equate one optical density reading to a specific number of bacterial cells without calibration against a known standard or a standard curve.
What is the optical density value of ethanol?
The optical density value of ethanol varies depending on its concentration and the wavelength of light being measured. At a standard concentration of 1 mg/mL, ethanol has an optical density value of approximately 0.25 at a wavelength of 220 nm. This value increases with higher concentrations and shorter wavelengths.
What is that optical density?
Optical density is the measure of the transmission of an optical medium for a given wavelength.Higher OD lower transmittence and vice versa e.g; optical density of 1 means 90% of incident light is absorbed.Optical density is the absorbance of an optical element for a given wavelength λ per unit distance: Where: : l = the distance that light travels through the sample (i.e., the sample thickness), measured in cm Aλ = the absorbance at wavelength λ T = the per-unit transmittance I0 = the intensity of the incident light beam I = the intensity of the transmitted light beamoptical density is the measure of the transmition of an optical medium for a given wave length.
What is the sine of angle of incidence divided by the sine of angle of refraction of equal optical density?
It is 1.
Volume to density 1ml water equals g?
1 gram (approx)
How many liters is 1 kilogram?
1 kilogram of water equals 1 liter.
How can you use density to determine whether an object will float or sink?
If any object has a density higher that 1 it will sink because water has a density of exactly 1. If the density is less than 1 it will float. Here is the formula for density...D=m/v or density equals mass over volume.
What does 2 mg equals how many cc's?
The conversion of milligrams to milliliters depends on the density of the substance. Without knowing the density, it is not possible to directly convert 2 mg to cc.
What is the density in grams per milliliter of a substance for which 1 pt equals 1 lb exactly?
Density = 1 lb/1 pt = 453.59 g/568.26 mL = 0.798 g/mL
If 1 is equal to 10 then 100?
If you meant 'If 1 is equal to 10 then 100 equals to what?' then the answer is: 'any number'.
How many kilograms in1 liters?
A kilogram equals a litre, IF density is 1 g/ml
