Very good question.

To make a body to move along a curved path it has to be massive. But photon, the quantum of light, is having zero rest mass and even in motion negligible mass.

If the particle is charged one, it can be driven along a curved path as in the case of charged particle in a magnetic field. But photon is charge less.

But light can be bent. As light falls on a glass prism, then the out coming light is found to be deviated towards the base of the prism.

By using the phenomenon of total internal reflection, light is easily taken through the optical fibres now a days.

Light can be assumed to be along a curved path as if we see that light passes through curved optical fibre. But the reality is not so.

With the idea of gravitational lens, of course, light can go along a curved path.

How can you curve light?

Light travels in straight lines on earth, so you can change its angle by refraction but not curve it. However over interstellar distances it has been observed that light is bent by gravitation.


What is a polar curve in terms of illumination?

The term "polar curve", in relation to the subject of illumination refers to the spread of light from a source. If the curve is weak, then little illumination is provided, whilst the opposite is true for a strong curve.
