There are rules like the the inverse square law, where it it often visualized that light travels in rays.
At first the rays are a lot and really dense, the further away the object it hits is, the lesser rays will hit it because it spreads harder than the object is big.
Now with the logic of a watering can. If the water streams would always spread the same amount, there should be places that never get hit by water depending on the distance of the object.
Can this happen with light? Are there blind spots of light even without any direct obstacle? Or does light travel like a wave hitting the shore, without gaps or something? I always wondered
Edit :This is super informative and interesting thank you alot Champs!

Using the analogies mentioned, it’s like a watering can that you keep shaking back and forth.
Photons (the “water droplets” that make up light) are emitted based on the movement and energy present in electrons (high energy particles that orbit atoms, the building blocks of everything). These particles aren’t released from the same place every time, and certainly aren’t released at the same angle.
Much like shaking a watering can, that means when you’re super close to the object in question, it’s almost guaranteed that you’ll hit every spot. This gets less and less likely the farther away you get.
