How may wave packets can fall on 1 square angstron ?

Question

Wave packet =I was told its the stuff that comes out of the Photons what ever they are.

Answer 1

It would depend upon the light being used.

An angstrom is a unit used to measure length with a magnitude of 1 E-10 meters.
1 square Angstrom is a unit of area, 1 Angstrom by 1 Angstrom.

Visible light is between about 400 nanometers and 700 nanometers.
1 nanometer = 1 E-9 meters......ten times larger than an Angstrom.
So visible light has a wavelength which is on the order of 4000 to 7000 times larger than the length of the square being used to collect light, in other words, you would not be able to "See" this 1 sq. Å object using visible light.

Using higher frequency, lower wavelength light (well outside the visible spectrum, X-rays or gamma rays) would make the object "visible".

But then comes the problem with counting the photon ("wave packets" as you call them). The number of photons depends on the intensity of the light....higher intensity, higher number of photons.
It is not as if a photon has a specific surface are or volume in which one could simply find a quick solution for.

If one really wanted to know the number of photons hitting a surface, what one might have to do is set up the experiment so that the photons (of a specific energy) contact the surface will energize the electrons around the atoms, causing them to jump into a higher orbital and measure this effect.

What is the reason for asking this question, where are you going with this?

Answer 2

about 3

Answer 3

hold on a second while i get out my dictionary.....

Answer 4

wat do u mean by wave packets???quanta???
