Answer:
from every point on the surface of the tree, and in every direction.
Step-by-step explanation:
The luminosity of an object refers to the total amount of light radiated by the object per second and it is measured in watts (w). Also, the apparent brightness of an object is a measure of the rate at which radiated energy from that object reaches an observer. Thus, the apparent brightness of an object is measured in watts per square meter.
Reflection can be defined as a phenomenon which typically involves a change in the direction of a ray of light or waves as it falls on a smooth surface.
Simply stated, reflection occurs when a ray of light or wavefronts bounces off a smooth surface.
When an object like a tree is illuminated by the sun, and you are looking toward the tree, light rays leave the object from every point on the surface of the tree, and in every direction.
This ultimately implies that, the light rays would be scattered in different directions because the tree has a rough surface. This phenomenon is known as diffuse reflection.
