ok xanthym, i get it now... all the whole thing.... i can grasp what u mean, but where did the 2nd formula came from in 3rd messsage?? is it a relationship in what?
space tiger, what i mean is how can i derive another formula, coz
tetha=1.22(lambda)/D
this is the only formula i know for now... since there is speed, how can i apply it to the formula... can u derive me some formula and can u explain it step by step...
Here is the problem...
Calculate the resolving power of a microscope with a 1.30cm aperture using 540nm light. The index of refraction of the lens slows the light inside the glass to 1.98x10^8m/s.
i just know the formula tetha=1.22(lambda)/D, but i dont know how to derive the formula since i...
how about for this problem...
Commercial satellites are able to resolve objects separated by only 1.0m. If those satellites orbit the earth at an altitude of 650km, determine the sixe of the satellites' circular imaging aperture. Use 455nm light for the light in the lenses of the satellites...
Help!! Single slit diffraction
heya all... this is the problem..
Predict whether violet light(lambda=404nm) or red light (lambda=702nm) will have a wider central maximum when used to generate a single-slit diffraction pattern. Calculate the difference if the light is incident on a 6.9x10^-5...
whozum.. ok i get the process and solution you gave to me, but how can i apply the two charges... should i find the F first for the two charges and what should i do next??
check this if this is right???
F/2N = 1.2x10^-11/4r^2
the new force i get is 6x10^-12N.. it is wrong, how can i get 0.17N? it's kinda hard to think about it...
magnetic fields
how about this problem...
Two identical object have charges of +6.0µC and -2.0µC, respectively. When placed a distance d apart, their force of attraction is 2.0N. If the objects are touched together, then moved to d distance of separtion of 2d, what will be the new force...
