REFRACTION OF LIGHT When a ray of light traversing a homogeneous medium falls on the bounding surface of another transparent homogeneous medium, it is found that the direction of the transmitted ray in the second medium is different from that of the incident ray; in other words, the ray is ...

Whereas primitive eyes can serve as simple dark/light sensors, sophisticated lens-containing eyes are often able to produce a sharp image in the desired plane of focus due to light refraction. Refraction occurs when light rays travel from a medium with a given refractive index to a medium with...

A light ray moves in a straight line when moving in a material medium. When the light ray transverses a material medium of different refractive index, it undergoes refraction. The refraction of light is identified as the bending of light and is caused by the change in the speed of ligh...
n = c/η As the refractive index of a material increases, the greater the extent to which a light beam is deflected (or refracted) upon entering or leaving the material. The refractive index of a medium is dependent (to some extent) upon the frequency of light passing through, with the...
Figure 31.8 shows an object O (a source of light) at a distance of more than twice the focal length from the lens. To determine the position and size of the image two rays only are drawn, one parallel with the principal axis and the other passing through the centre of the lens. The...
Therefore, the refractive index (n) is inversely proportional to the wavelength and also to the speed of light. This means the greater the wavelength, the lower the refractive index. This relationship is represented by the equation: v(λ) = c/n(λ) However, for i...
