A thin prism of2∘angle gives a deviation of1∘. What is the value of refractive index of the material of the prism. View Solution A prism of refracting angle60∘is made with a material of refractive indexμ. For a certain wavelength of light, the angle of minimum deviation is30...
Relative refractive index is defined as the ratio of the light velocities between any two media other than a vaccum (or air). For example, one could measure the refractive index of olive oil relative to the refractive index of water. However, there is no practical use for measuring relative...

The force acting on a micro-sphere with refractive index less than its surrounding medium by a TEM00 mode focused light beam is investigated both theoretically and experimentally. It is demonstrated that although the force is mainly a repulsing one, optical trapping is available in the cases in...
Therefore, a grating with κL greater than one (κL > 1) is termed a strong grating and a grating with κL less than one (κL < 1) is a weak grating. 5.3.1.6 Bandwidth of the Grating. The other important property of the grating is its bandwidth. It is a measure of the ...
in ordinary glass the refractive index for violet light is about one percent greater than that for red light. A consequence of this phenomenon is that each wavelength experiences a slightly different degree of refraction when a heterogeneous light beam containing more than one frequency enters or le...
The definition is this: refractive index is the degree of bending that occurs when light enters this material from the vacuum. The refractive index of a vacuum is 1. Refraction occurs when light enters other materials, and the refractive index of other materials is greater than 1. ...
Refractive index is one of the most important properties in optical glasses. Therefore, a large number of researchers have carried out investigations to ascertain the relation between refractive index and glass composition. The values obtained in the Bi2O3–SrO–TeO2 system are much higher than tha...
(b) Can absolute refractive index of a medium be less than one ? Given reason. View Solution The refractive index of a material will be less than unity when View Solution The aboslute refractive index of any medium is always View Solution Refractive index of a medium depends on View ...
