What is a ray of light?

Show that the line integral of electric field ntensity between any two points depends only on the position of these points and its independent of the path followed between these points.

Brighter light means more photons, not more energetic photons. (True/ false)

A beam of unpolarised light is incident on the boundary between two transparent media.If the reflected light is completely plane polarised,how is its direction related to the direction of the corresponding refracted light?

A ray of light is incident normally on one of the faces of a prism of apex angle 30^@ and refractive index sqrt2 .Find the angle of deviation for the ray of light.

A ray of light is sent through the point P(1,2,3) and is reflected on the XY plane. If the reflected ray passes through the point Q(3,2,5) then the equation of the reflected ray is
