The redshift that scientists speak of in stars, indicating that they are moving away, is complemented by a shift toward the blue in the spectrum by light moving toward a viewer.
You would either position the object creating the shadow perpendicular to the light source or move it closer to the light source.
the shadow becomes bigger
The wavelength will be shorter!
As an object moves closer to a concave lens, the virtual image, that is created on the same side of the lens as the object, will remain upright but will be reduced in size.
When you include the effects of friction, it takes less force to move a light-weight object. If you can get the objects into a frictionless environment, then any force, no matter how small, can move any object, no matter how heavy.
You can either move closer to the light source or move the light source closer to you. The size of your shadow just depends upon how much of the light you are obscuring so the more you block out, the bigger your shadow.
It depends what you move it closer to.
Simply take a step forward in the direction of the object you want to move closer to. Alternatively, you can physically move your body or adjust your position until you reach the desired distance from the object.

A: Heat from the room will move to the cold object. B: Condensation will happen
Move the light source farther away from the object.
Move the objects closer together.
farther away
No object that has mass when it's just sitting there on the table can move at the speed of light. Photons have zero "rest mass".
