When light rays from an object are incident upon an opaque, rough-textured surface, no reflected image of the object can be seen. This phenomenon occurs because of ____.

• regular reflection
• diffuse reflection
• reflected angles not being equal to incident angles
• reflected angles not being equal to refracted angles
