Rectilinear propagation is the phenomenon in which light waves travel in a straight line without changing direction. This occurs when the light waves interact with an obstacle that does not curve or bend around them.
A clear example of rectilinear propagation is the propagation of light through a rectangular slit. Light passing through the slit will travel in a straight line and create an interference pattern on a screen behind the slit.
Another example of rectilinear propagation is the propagation of light through a windowpane. Light passing through the windowpane will travel in a straight line and create a shadow on the ground outside the window.
The speed of light is constant, and this means that light waves will always travel in a straight line. This property of light is responsible for the straight-line propagation of light
