the power flux reaching the earths top(via sun ,visible light) is 1400 watts/m^2 this is much more than 500W you are talking about so why are we not blinded then.......what is the power of visible light emitted by light bulb i guess its more than 1W at least....
concept is not yet clear...
visible light has a frequency higher than microwaves ....yet microwaves are very harmful to human body
but visible light is not(it has high frequency and energy so it can penetrate human body more)
i cannot figure out the reason for this please HELP!!!!
Digital Image Processing - Rafael C. Gonzalez is a complete package
but if u have a time constraint and want to learn faster u should download image processing codes from net and try to understand various functions believe me its much faster.
u can start with a basic red color tracking code...
i want to interface my FPGA BOARD(spartan3E) with my sony camera(10Mp) and view its video on VGA display
now the problem is that when i interfaced VGA with fpga i had a manual tellin about how data goes to VGA port (and about horizontal synch,backporch,front porch etc.) but i cannot find any...
optical fibres work on the principle of total internal reflection...for that angle of incidence has to greater than a particular critical angle...now my TV transmission from my d2h antenna to my settop box is also via optical fibres .....
so if i bend the wire completely the angle of incidence...
thanks for your time , good explaination

the other person cannot see through my head he'll have to have X ray vision for that...although it'll damage my brain cells...so touche
we could try using something other than X-ray with higher freq. but not dangerous...P.S can we generalize the statement that if the frequency is very high then the wave would certainly be dangerous(because of more energy in it)
why do we not use high frequency waves such as X rays , gamma rays etc. instead of radio waves for communication . coz their modulation is easy larger bandwidth,speed and shorter antenna?????
If in a circuit there is just a battery source (DC), a capacitor and a resistor all in series ,the will the current flow in the circuit????.....because ideally capacitor blocks DC and no current should flow in the circuit....
but in many numericals of circuit theory i see that these type of...
