Observation
The observation of an objective from an observation post (OP)
it is observation
An observation can be anything you observe through your five senses: sight, smell, touch, hear and taste. Anything that you can describe would be considered an observation.
I can give you several sentences.Careful observation will reveal that the burglar had a key.The scientist began his observation of the strange rock.You powers of observation are amazing.
'No visible grain' refers to a rock's texture, and the inability to distinguish individual particles or crystals by simple observation without magnification.
observation is observation! :)inference is inference! :)Assuming you meant "Differentiate observation from inference ?" !....Observation is the act of being able to physically see an object - inference is implying something is real without physical proof of its existence.Incidentally - why was this put into the category 'animal life' !
The Sun produces all the electromagnetic radiation in the visible and near visible range. UV rays are near visible ultraviolet rays.
Direct observation, including participant and non-participant observation, ethnographic diaries, and more recently Photography and video. Hope this helps!
=Science is a systematized body of knowledge which deals on the observation and classification of facts from which conclusions are derived. =
Tracer
Where visible light is present, you may be inadvertently and unwittingly thrust into the situation where you see things that you were not meant to see, or that you would rather not see.
A single atom is not visible in a microscope (it is too small to be imaged by photons). What you see in an optical microscope (or in general) is the light reflected, scattered, or emitted by the electron layers of the material under observation.
The rock would have visible mineral crystals--a phaneritic texture.
Tracer ammunition.

It's called a tracer.
