The correct answer is When we set the object adjacent to the flashlight and not exactly into its beam of light, we probably won't initially notice a shadow. However, if we place the object directly in the path, we should be able to see a shadow of it on the wall.
What is shadow?
A shadow, or black area, is produced when an opaque object deflects light from a light source. Behind a light-emitting gadget, it fills the entire three-dimensional space. A 2-D backward projection of the object obstructing the light can be used to conceptualise the cross section of a shadow.
Light goes in a straight line, therefore placing an object next to a flashlight but out of the light's direct path prevents us from seeing a shadow. Since the object was out of the light's direct path, it was unable to block the light from the flashlight's source.
