That will scatter.
it depends on the surface. the ability for a light wave 2 "bounce off" lies in whether or not the substance will absorb that certain frequency of light...and the type of surface (i.e. smooth or rough)
what occurs when parallel rays of light hit a rough or a bumpy surface
Parallel light rays which fall on a smooth surface(a mirror) are reflected as parallel rays. This is called REGULAR REFLECTION. Whereas, parallel rays which fall on an irregular surface(The ground) are reflected in different directions. This is called irregular reflection.
smooth surface
dont bounce it off cement or other hard rough surfaces and keep them out of the rain or wet areas.
Scattering of light.
light colored and smooth. these characteristics will allow the waves to reflect and bounce off rather than absorb.
Scattering. Yes.
Some light that falls on any surface is scattered back (reflected). A rough surface tends to scatter the light in different directions while a smooth surface tends to scatter more of the original (incident) rays straight back. This explains why a smooth surface reflects a "clearer" image than that reflected from a rough surface.

it help people to see in dark
