how do u make a one photin in beam of light

Answer:
Hi mate
Explanation:
The energy of a photon is E = 7.8×10−20j. Let us consider a 1000 watt light source, which is comparable to direct sunlight. This light is about 1.3×1022 photons per second.
Answer:
There is no such thing as a one-photon-thick beam of light. Photons are not solid little balls that can be lined up in a perfectly straight beam that is one photon wide. Instead, photons are quantum objects. As such, photons act somewhat like waves and somewhat like particles at the same time. When traveling through free space, photons act mostly like waves. Waves can take on a variety of beam widths. But they cannot be infinitely narrow since waves are, by definition, extended objects. The more you try to narrow down the beam width of a wave, the more it will tend to spread out as it travels due to diffraction. This is true of water waves, sound waves, and light waves. The degree to which a light beam diffracts and diverges depends on the wavelength of the light. Light beams with larger wavelengths diverge more strongly than light beams with smaller wavelengths, all else being equal. As a result, smaller-wavelength beams can be made much narrower than larger-wavelength beams. The narrowness of a light beam therefore is ultimately limited by wave diffraction, which depends on wavelength, and not by a physical width of photon particles. The way to get the narrowest beam of light possible is by using the smallest wavelength available to you and focusing the beam, and not by lining up photons (which doesn't really make sense in the first place).
