What should be placed in front of main door?

What should be placed in front of main door? A clean house, especially the main door entrance, attracts positive energy. Avoid keeping dustbins, broken chairs or stools, near the main door.

Subsequently, is light attracted to anything?

No, light only travels in straight lines (according to the local geography). It is not attracted by anything, especially other photons. Moreover, what's inside a photon? In physics, a photon is a bundle of electromagnetic energy. The photon is sometimes referred to as a "quantum" of electromagnetic energy. Photons are not thought to be made up of smaller particles. They are a basic unit of nature called an elementary particle.

Can photons hit each other?

Since light itself does not have electric charge, one photon cannot directly interact with another photon. Instead, they just pass right through each other without being affected. However, two photons heading towards each other can indeed collide indirectly. What would a room made of mirrors look like if there was nothing inside that room to create a reflection? The simple way to put it is this; if there is nothing in the room, there is nothing for the observer to see. And if there is no light in the room, there is no way the observer can see anything. An empty room of mirrors will look like a vacuum of nothingness.

People also ask what happens if there are no spherical mirrors?

1) Their important role in hospitals, rear-view mirrors, would have been incomplete. 3) Use of convex mirrors in ATMs, computer monitors, sun glasses would not have been possible. 4) It would not have been possible to observe small objects as big if concave mirrors were not known. Is there a perfect mirror? A very complex dielectric mirror can reflect up to 99.999% of the light incident upon it, for a narrow range of wavelengths and angles. Almost any dielectric material can act as a perfect mirror through total internal reflection.
