why do i see negative peaks when reading for bragg wavelengths from a photodetector using a A/D indicators? i dont understand why i see negative peaks on my A/D indicator when i use it to read bragg wavelengths from a photodetector for voltage vs time, yet no negative peaks will appear for a wavef

what does the location of the peak detector mean
