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.
is the two human body have different refractive index
What is carvedilol phosphate Refractive index in Hexane
Refractive Index of water=1.333 Refractive Index of Sea water=1.343
The refractive index is 1,46-1,46 at at 20 oC.
energy mass refractive index
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: 1.4465
Refractive index of vacuum is 1.
Refractive Index: 2.4175-2.4178
"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)
The refractive index is determined experimentally.
The absolute refractive index of kerosene is 1.39 .
The absolute refractive index of kerosene is 1.39 .
is the two human body have different refractive index
refractive index is equals to squarroot of relative permitivity
