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/v
Absolute 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 are the differences between and airtrain and a vene ?? what are the differences between and airtrain and a vene ??
No. Without refraction at a boundary between media with different refractive indices, lenses wouldn't work. The only way we would have of forming real images would be with curved mirrors.
nothing
difference between cvp and bep
not in my books
There is no direct relationship between viscosity and refractive index. Viscosity relates to the resistance of a fluid to flow, while refractive index is a measure of how much light bends as it passes through a substance. However, the refractive index of a substance may change with temperature, which can in turn affect its viscosity.
yes
The bonding energy depends on differences between electronegativities.
It depends on (a) the angle of incidence, and (b) the relative refractive indices of the slabs as well as the medium on either side of them and between them.
The differences in spectrum are mainly due to: * Differences in temperature between the stars * Differences in chemical composition * Differences in relative movement (redshift / blueshift, due to the Doppler effect)
Quartz is a mineral composed of silicon dioxide, while diamond is a gemstone composed of pure carbon. Diamonds are much harder and have a higher refractive index compared to quartz. Additionally, diamonds are formed under high pressure and temperature deep within the Earth, while quartz is formed under a variety of conditions in the Earth's crust.
When a wave travels from one medium into another at an angle, it undergoes refraction, meaning its direction changes due to the change in speed as it moves from one medium to another. The wave will bend either towards or away from the normal (a line perpendicular to the boundary) depending on the change in the wave's speed between the two mediums.
Properties differences between liquid and solis water: density, specific heat, standard molar entropy, refractive index, thermal coductivity, the liquid has viscosity etc.
Prof. Baumer much lol.
A fall in a country's exchange rate will lower its relative wage, and a rise in a country's exchange rate will raise its relative wage.Microeconomics
the angle between the refracted ray and the normal
Humidity is the amount of water vapor present in the air. The relative humidity is the measure of the amount of water vapor present in the air compared to the amount needed for saturation.
