it is a unitless number because it is the ratio of speed divided by speed. in other words m/sec divided by m/sec. the units cancel leaving just a unitless number.
To find the refractive index of groundnut oil, you can use a refractometer designed for measuring the refractive index of liquids. Place a drop of groundnut oil on the refractometer's prism and then measure the refractive index value displayed on the scale. This will give you the refractive index of groundnut oil.
is the two human body have different refractive index
The refractive index of glass is around 1.5, while the refractive index of water is around 1.33. This means that light travels faster in water than in glass. The difference in refractive index is why we observe light bending when it passes from air into glass or water, a phenomenon known as refraction.
Changing the pH the chemical composition is changed; as a consequence the the refractive index is influenced.
The speed of light in any medium isspeed of light in vacuum/refractive index of that medium.
I assume "molecular refractive index" refers to "the refractive index of a group of molecules". In this case, you just use the units for a refractive index - i.e., a dimensionless number.
Refractive index of the medium is defined as the ratio of the velocity of light in vacuum to that in the medium. No unit for refractive index.
Refractive index of vacuum is 1.
Refractive Index: 1.4465
"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
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)
What is a prism and how does it relate to the refractive index? Explain how the refractive index of a prism affects the bending of light. How can you experimentally determine the refractive index of a prism?
The refractive index is determined experimentally.
The absolute refractive index of kerosene is 1.39 .
The refractive index of diamonds is approximately 2.42. This high refractive index contributes to the diamond's brilliance and sparkle when light enters and exits the stone.
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.
To find the refractive index of groundnut oil, you can use a refractometer designed for measuring the refractive index of liquids. Place a drop of groundnut oil on the refractometer's prism and then measure the refractive index value displayed on the scale. This will give you the refractive index of groundnut oil.
