What number indicates how optically dense a substance is?
I predict you are talking about the refractive index. the higher the value, the more dense the substance and thus light undergoes greater refraction (bending of light as it passes thru different mediums) the refractive index = sin of the angle of light made with normal in the less dense medium divide by the sin of angle in the denser medium.
What medium has higher refractive index?
Generally, denser mediums have higher refractive index. For example, water has a higher refractive index compared to air. Similarly, glass has a higher refractive index than water.
What is Optical denser medium?
Optical dense refers to the index of refraction. If one medium is optically denser than another, then its index of refraction is larger, meaning the speed of light in the optically denser medium is smaller.
How speed changes in different mediums?
Speed changes in different mediums due to variations in density and composition of the medium. In general, speed is slower in denser mediums and faster in less dense mediums. For example, light travels faster in air than in water due to the difference in density and refractive index of the two mediums.
What are the conditions for total internal reflection to take place?
Light must travel from the optically denser medium to the optically less dense one. For total internal reflection to occur, the angle of incidence in the optically denser medium must be greater than the critical angle of that medium. The critical angle is that angle of incidence in the optically denser medium for which the angle of refraction is 90o.

If one medium is in kept in another medium of same refractive index - will it be visible?
No, if the refractive indexes of the two mediums are exactly identical it will be invisible.
How do you find the refractive index of a liquid by using a convex lens and a plan mirror?
Using Snell's law, n(1)=(n(2) x sin angle (2)) / sin angle (1).n(1)= The refractive index of the more optically dense medium.n(2)= The refractive index of the less optically dense medium.angle (1)= The critical angle of the two mediums.angle (2)= 90 degrees since when light is at the critical angle it undergoes total internal reflection.Since sin 90= 1, this can be ignored, resulting in n(1)= n(2) / sin angle (1)
Does water or air have the highest refraction index?
Actually we define refractive index with respect to a standard medium. Air has been taken as that standard. Hence refractive index of air is 1 and that of water is 1.33. But refractive index of water with respect to glass is 1.33/1.5 = 0.887 So, the answer is "water".
Why do different mediums bend light at different angles?
Different mediums have different refractive indices, which determine how much light is bent as it passes through them. The refractive index is a measure of how much the speed of light changes in a medium compared to its speed in a vacuum. The higher the refractive index of a medium, the more the light is bent as it enters or exits that medium.
Which way will light bend when passiing from air to quartz?
The refractive index of air is about 1.0003, and of quartz about 1.45, so quartz is the more "optically dense" medium in this situation. When light goes from a less dense medium to a more dense medium, it is refracted toward the normal. The normal is the imaginary line perpendicular to the surface where the light enters.
What happens to the wavelength of the wave as it passes into Medium 2?
The wavelength of the wave can change as it passes into Medium 2, depending on the refractive indices of the mediums. If the wave enters a medium with a higher refractive index, the wavelength will decrease. If it enters a medium with a lower refractive index, the wavelength will increase.
What is the refractive index of vacuum?
Refractive index of vacuum is 1.
