I was doing a practical to analyse for my school assessment with regard to Planck's constant. I was using a Planck's constant kit to get some results but the results I was getting was inconsistent with my research as seen below. Isn't the voltage meant to increase as the wavelength is shorter? My results seem really muddled up and I did it again and it still came out with the same results. Perhaps there is something wrong with the machine or is this just the way it is meant to be?
