True Friend - Osho

Friendship is possible between equal human beings, totally free from all bondage of society, culture, civilization, only living true to their authentic nature.

My Friend

A man who seeks friendship, love, companionship, out of loneliness is not going to find it. In fact, with whomsoever he will associate he will feel cheated and he will make the other feel cheated. He will feel tired and bored, and he will make the other feel tired and bored. He will feel sucked and he will make the other feel sucked, because both will be sucking on each other’s energies. And they don’t have much in the first place. Their streams are running very thin; they are like summer streams in a desertland. You cannot take any water out of them. But if you seek friendship and love and companionship out of aloneness, you are a flooded river, a river in the rains. You can share as much as you want. And the more you share, the more you will have.

INTERFERENCE

Interference effects in light waves are not easy to observe because of the short
wavelengths involved. For sustained interference
in light waves to be observed, the following conditions must be met:
• The sources must be coherent—that is, they must maintain a constant phase
with respect to each other.
• The sources may be monochromatic—that is, of a single wavelength.
We now describe the characteristics of coherent sources. As we saw when we
studied mechanical waves, two sources (producing two traveling waves) are
needed to create interference. In order to produce a stable interference pattern,
the individual waves must maintain a constant phase relationship with one
another. As an example, the sound waves emitted by two side-by-side loudspeakers
driven by a single amplifier can interfere with each other because the two speakers
are coherent—that is, they respond to the amplifier in the same way at the same
time.

Physics of Optics

Optics is a branch of physics that is concerned with behaviour and properties of light. It mostly cares about visible light, since it’s easiest to perceive and thus research and understand, but other electromagnetic waves are also involved- from x-rays through infrared and ultraviolet to radio and micro waves.

 science concerned with the genesis and propagation of light, the changes that it undergoes and produces, and other phenomena closely associated with it. There are two major branches of optics, physical and geometrical. Physical optics deals primarily with the nature and properties of light itself. Geometrical optics has to do with the principles that govern the image-forming properties of lenses, mirrors, and other devices that make use of light. It also includes optical data processing, which involves the manipulation of the information content of an image formed by coherent optical systems
