Because if it is opaque it is blocking the light.
Be careful not to confuse: Opaque objects are those that do not allow light to pass through it, but they can reflect light. It is BLACK objects that absorb all the incident light on it. To conclude, opaque objects do not necessarily absorb all the incident light on them but black objects ABSORB all the incident light on them (and are, of course, opaque)
A rock, a tree and a dog are three opaque objects that stop or absorb light
are all opaque objects reflectors
Opaque objects do not let light to past through so it will not cause a shadow. Because light cannot get through an opaque object, it will cast a shadow on the side opposite of the light.
Why can't light pass through what? To first contributer, don't say that. Say light cannot pass through solid, opaque objects at times.
Light microscopes can observe objects of 100 nm- 1 mm. Electron microscopes can observe objects of 1 nm-100 µm.

No, not objects that are opaque.
These objects are opaque.
White Light
opaque objects
Not let light through them :D
