An LED that emits light of wavelength λ = 614 nm illuminates the phototube. A reverse bias is applied to the phototube (a voltage that opposes the current flow). This is adjusted carefully until the photocurrent drops to zero. The stopping potential is found to be Vo = 0.162 V. The LED can now be changed and the process repeated for a different λ. Then the data can be plotted to determine Planck's constant, h. For the data collected above...

Blue light of wavelength 470 nm is used to illuminate a pair of narrow slits that are 0.020 mm apart and 1.60 m from a screen. (a) What is the angular position of the second-order minimum (dark spot)? (b) What is the distance on the screen between the central maximum and the second-order minimum? (c) The reason there is a dark spot at this location on the screen is because light from one slit has to travel further than light...
