Each oil has a specific refractive index.
When using the oil immersion objective, the oil has the same refractive index as the glass. So it is like an extension of the lens. Water does not have the same refraction index as glass, so the image would not be as clear.
Immersion heaters are used for heating water in a hot water tank. Immersion heaters are usually controlled by thermostat and they will heat your water to a set temperature for as long as you leave it on that setting, or you can have a timer set. It is usually an expensive way to heat water compared to central heating systems with hot water circuits.
You can experience collapse of arterial blood pressure, leading to cardiac arrest.
glass feels smooth and glass is made from sand and water =]
this is called condensation in the water cycle it forms water droplet because when the liquid turns into gas the particles move and when they spread apart and float away some get stuck on the sides of the glass cup. Then with enough of the gas particles come together turning it into droplets and goes back into water to do it all over again.
Each substance has an index of refraction. The index of refraction of water is about 1.3330 . The index of refraction of air at standard conditions is about 1.0003 . There is no such thing as the index of refraction of "water to air".
The power of a lens depends on the differences in the refractive indices of the environment and the lens material. A glass lens immersed in water will loose power (a positive lens will focus at a greater distance). (This is for normal glass with refractive index greater than water - there could be glasses with refractive index less than water in which case the lens would gain power)
When using the oil immersion objective, the oil has the same refractive index as the glass. So it is like an extension of the lens. Water does not have the same refraction index as glass, so the image would not be as clear.
"The refractive index of water is 4 / 3" means the refractive index of water with respect to air. "The refractive index of glass is 3 /2" means the refractive index of glass with respect to air. You change the question as ," what is the refractive index of glass with respect to water? The answer is it is the ratio of refractive index of of glass with respect to air to the refractive index of water with respect to air =( 3/2) divided by( 4/3) = 1.125

Glasses of various types have refractive indices ranging from 1,4 to over 2,0
Gets refracted more in case of glass than water as glass has higher refractive index with respect to air
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".
The speed of light in any medium is given by its speed of light in vacuum divided by the refractive index of the medium and so light will travel faster in water than in glass since refractive index of glass is greater than that of water.
The graph of Snell's Law is used to calculate the Refractive Index of a material. Sin (i) over sin (r) gives you your refractive Index. This is diffrent for Diffrent materials. IE refractive Index in a: Vaccum = 1 Water =1.33 Glass = Average of about 1.5, depending on what type of glass Diamond = 2.42 Air (STP) = 1.0003
Refractive Index(i) Refractive index of a medium is that characteristic which decides speed of light in it.(ii) It is a scalar, unit less and dimensionless quantity.(iii) Absolute refractive index :When light travels from vacuum to any transparent medium then refractive index of medium w.r.t. vacuum is called it's absolute refractive index i.e. vacuumµmedium = c/vAbsolute refractive indices for glass, water and diamond are respectively µg = 3/2 = 1.5, µw = 4/3 = 1.33 and µD = 12/5 = 2.4(iv) Relative refractive index :When light travels from medium (1) to medium (2) then refractive index of medium (2) w.r.t. medium (1) is called it's relative refractive index i.e. 1µ2 = µ2/µ1 = v1/v2 (where v1 and v2 are the speed of light in medium 1 and 2 respectively).(v) When we say refractive index we mean absolute refractive index.(vi) The minimum value of absolute refractive index is 1. For air it is very near to 1. ( 1.003)
