Rectilinear propagation of light theory states that light travels in a straight line.
A freely falling body A car moving along a straight road. Light too has rectilinear propagation.
Tyndall Effect and Formation of Rainbow
(1) The principle of camera depends on it (2)Periscope- its mode of action dpends on the rectilinear propagation of light
I could say that, although it would be simpler to say that shadows are made possible by the fact that light normally travels in a straight line.

Rectilinear propogation of light.
From rectilinear propagation of light.

Lignt being a wave must express the phenomenon of bending at the edges. But this is not easily observed. This is mainly because of the shorter wavelength of light. Hence we come to the conclusion that light never bends and always travel in straight lines. This is what we call rectilinear propagation of light. This was successfully explained by Young and Fresnel with the concept of half period zones. Also light waves considered as transverse in nature.
Includes tyndall effect,shadow formation,rainbow formation,eclipses athough your question should be based on effects.
Light travels in astraight line as it has the property known as the rectilinear prpogation of light.
