Stealth vs Invisible

For the past 8 years in military equipment and firearms involment,
along of friends and customer always ask me to diffrentiate some
term for them.

One of the frequently asked question was : What are the diffrences
between stealth and invisible. A lot of local military high ranking
people also asked me this question.

Well, I always tell them using the simple way.

Stealth = Something which is difficult to detect or notice.

Invisible = Something which you can't see using naked eye under normal
lightwave.

Ok let's put example and explaination.

Stealth figther F-117 Night Hawke. US first mass production single seated
stealth figher. It is difficult to notice cause it :
  • Normally flies by night.
  • Painted by black or dark colour.
  • Has radar absorbtion surface. Hence reflexing minimum or nil radar.
  • Has good exhaust heat "silencer".

    So this aircraft is Stealth in sense of it is difficult to be detected by
    radar or can't be seen during the night cause it is black colour. This
    is stealth...

    Let's define invisible = ( in=can't & visible= able to be seen )
    Invisible, actually invisible is very difficult to achieve. Cause something
    can't be just made invisble.

    For example, could a person become invisible? Nope I don't think so this
    could be done using today's technology. Anything which has mass like human,
    metal, water, and anything in the world is visible.

    Even, air when compressed into liquid it become visible. And water is visible
    cause the wave above it and the refection of lights let us "see" it.

    Invisible Fighther? Yes Malaysia has about 20,000 unit of Invisible F-117 with
    the latest weapon. Have you seen it? I don't cause they are all invisible.
    But I am sure they are somewhere around Subang, Sungai besi and Kuantan air
    base. I am sure that they are there.

    You have any idea what I am talking about? Sorry but I don't... heheheh

    Too much of durian and I am kena durian food poisoning... kekekek !!
