Thanks a lot to you guys. I appreciate every answer of you and it definitely helped me to find a way of how I should classify my problem. I started to try to get to the bottom of it and obviously mixed up a lot of things which has led me to my mess. I again say thanks to all the posts and...

Ok either I'm really very confused about this or I don't know how to write up my question neither in my language nor in english. I do know about waves, wave reflection and also, that the waves have to reach the eyes. And I posted this in this forum because I started thinking about this, when I...

Why are electromagentic waves not visible itself but visible if they are reflected by an object ? Assuming a source of light emitting photons. This waves are not visible in the dark. If they end up on a surface of any object which "reflects" the light we start to see the object. What happens at...

First of all thanks for answering. Thanks for your note Claude. I will change this but I also got the right values writing it like integers. So is there any other way, I could use the recursive code with? @SteamKing I later recognized, that its implied do and not implicit after reading some...

Hello there, I again have a problem with programming in Fortran 90.1. Homework Statement I would like to construct an array with an implicit do loop. I know how to get the array I want to with usual do-loop but I would like to do it without do loops. So this is the array I want to construct...

Hey Mark44, thank you very much for your answer! I already solved the problem by using an allocatable array. The thread can be closed. Thanks. greets Boltzmann

Hello, I'm new here and I'm also new in programming. I never did it before and now I have a problem with one of the programs in fortran 90 and I can't figure out how to solve it. Maybe some of you can help me. Many thanks in advance. 1. Homework Statement I need to plot the results of a...

Hello, there's not a lot to say. I'm a 23 year old physics student in Vienna. I started last year. Hope to find some answers here :D greets
