The text says ' In the Circuit below, the diode has a reverse saturation current Is= 10fA, a device factor n=1 and is operated at a temperature of 300K . Find values of resistance Rf and voltage V2 which will produce an output voltage. Vout = ln (Vin)'

Homework Statement Hello, I am trying to Calculate The Resistance Rf and the value of the Voltage V2. The setup is a logarithmic Op amp connected to a differential Op amp. Both Op amps obey the Golden Rules. Attached below is my attempt at the solution and the question. Currently, I have an...

Error analysis sorry for typing 0.3mm, i was looking at the wrong points, the distance between maximum 1 and 2 is 1.25mm and between maxima 2 and 3 it is 1.2mm, so an error of 0.05mm. thank you for clearing up the error on the wavelength. After checking with the lab manual i see that we used a...

Thank you for the response ehild After reading through the page I saw that the formula for N slits was As oppose to my formula for two slits. The website denotes p as the pairs of slits. I am ensure to what I would use for this value. I assume N is the total number of slits. I assume...

Thank you for responding BvU I see your point about making things clearer. Experimental Set up in 2d.png To start with i have attached a rough 2d sketchup of the experimental setup mounted onto an optical bench. The equation I have used Is based on the intensity distribution for single slit...

Homework Statement Hi The experimental setup involved a helium neon laser of wavelength 670nm +- 1nm, pointed towards a lens with focal length 500mm +- 1mm. (so that the equations used corresponded to the far field diffraction pattern) and onto a photo diode so that for all intents and...
