hi, anyone can guide mee to where I can find the answers to the questions below:
1_ what is the physical structure of a holographic film. I know we are talking about cristals, I am more intersted in their structure, their separation from each other - if any
2_ after the light and phase have been recorderd, what is their structure then?
I am guessing each will "diffract" (sorry english is not my main language)) the light in every direction, this donee by each cristal (or group of cristals) how does it work physically with its impact on the optic side (is the beam just bouncing back, how is it de-pahased if it is....
is the change of phase due to the height of the layers (with the diferent speed of light in it, making it slower to travel, therefore) when travelling into more of the layer, it will come out dephased more.

I know the above might sound weird, but that is why I ask.
please provide links in the answers.

If not does the number of atoms increase with a If so how does the current increase, is it because there is greater space between the atoms and therefore free electrons can ionise the atoms more easily?

A charge of +q is located at the origin, while an identical charge is located on the x axis at x = 0.60 m. A third charge of +2 q is located on the x axis at such a place that the net electrostatic force on the charge at the origin quadruples, its direction remaining unchanged. Where should the third charge be located?

I just filled a plastic juice bottle, and noticed that the sound of the water filling the bottle rose in pitch as the bottle filled up. Before, I just took it for granted that the pitch rose as liquid filled something, but now I'm wondering why.

I'm a singer and lyricist, but not a physicist.

Any ideas opn how to do this?? please try to answer both questions.

A skater with a mass of 52.0 kg moving at 2.5m/s glides to a stop over a distance of 24meters. How much work did the friction of the ice do to bring the skater to a stop? How much work would the skater have to do to speed up to 2.5m/s again.

surface,the waves get reflected and travel parallel in to the air" i cant understand that ,does the source kept (on a dish antenna which is a parabola) transmit the waves back on to the dish surface first ,which are then reflected into the air for transmission,or if u cant understandmy question ,plz tell me the working of dish antenna which is parabolic in shape

in the whole universe there is no an identical proof or example which shows a behavior like "a straight line" and "parallel lines"

it is just a theory which never exists in reality. even one talks about a light's path, the path of light is also affected by the maganetic force. no single thing is scapeable outside the boundry.

Hence, In this whole universe the concept of a straight line and paraell lines obselete. we can't proof it mathematically and physically. if one says we can remove gravitational force or maganetic forces in the way of light, but this wont meet the actual "fact". a fact is fact which testified everywhere with same behavior and results

If the BB is correct, at the moment of the explosion, the laws of physics began their 'appointed/determined/by chance tasks.
In so far as I understand it then, the laws pf physics were present before time began, eh?
