If the light hits a plane surface, regular reflection will take place and if light hits a rough surface, diffused (irregular) reflection will take place. Here is a diagram for both.
Diffused (irregular)
Regular
The light rays are deflected off at the same angles as the angles on the rough surface.
No, it is not.
It wavers
what occurs when parallel rays of light hit a rough or a bumpy surface
It can reflect off a rough surface but the image is not clear ,causing an irregular reflection.
Reflection of light from a rough surface is known as "Diffused" or "Irregular" reflection, because the light rays are barely seen after the reflection of light from a rough surface.
when light hits a rough surface it scattters.
A flat plane mirror produces regular reflections since its polished reflective surface is flat compared to the wavelength of light. If the surface is rough or irregular compared to the wavelength, the light will be scattered, resulting in diffuse reflection.
The light rays are deflected off at the same angles as the angles on the rough surface.
No, it is not.

what occurs when parallel rays of light hit a rough or a bumpy surface
When light strikes a rough surface it reflects in essentially random directions.
It can reflect off a rough surface but the image is not clear ,causing an irregular reflection.
The light is scattered. Some of the light may be absorbed, depending on the surface.
When light strikes a smooth surface (like a mirror), it is reflected. When it hits a rough surface (like a sheet of paper) it is diffused, meaning the rays of light are scattered.
