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.

It is 1.
Volume to density 1ml water equals g?
1 gram (approx)
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'.
2x plus 3 equals 4x2?
If you meant 2x+3=4x²x=(1±√(13))/4x1≈1.151387818866x2≈-0.651387818866
1 optical density equals how many bacterial cells?
10^6 cell but it varies species to species bacterial cell..
What is the sine of angle of incidence divided by the sine of angle of refraction of equal optical density?
It is 1.
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 density of a liquid?

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.
How many liters is 1 kilogram?
1 kilogram of water equals 1 liter.
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 an object has a mass of 5 grams and a volume of 10 cm cubed what is the density of the object i also need to show how i worked it out?
m divided by v equals d where d equals density, v equals volume and m equals mass SO.... 5 divided by 10 would be .5 or 1/2 THERE YOU GO!!! m divided by v equals d where d equals density, v equals volume and m equals mass SO.... 5 divided by 10 would be .5 or 1/2 THERE YOU GO!!!
How do you find the density of something?
you have to know the mass and volume of the object. density equals the mass divided by the volume. if the mass of something was 5 and the volume 1 the density would be 5
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
