Question

which statement best describes how light waves travel in a uniform medium?

in bent lines

in shrinking ripples

in extending circles

in straight lines

Explanation:

Light travels in straight lines (rectilinear propagation) when moving through a uniform, homogeneous medium. Bent lines occur during refraction/ reflection in non-uniform media, ripples/circles describe wavefront expansion but not the direction of travel in a uniform medium.

Answer:

in straight lines
