please explain how the answer to the questions are correct give a full explanation as to why the answer is what it is Question: Question A.1 (1 points) What is the cutoff wavelength Acutott for sodium and what is your uncertainty in this wavelength? Provide the following two explanations: • Explain what you are looking for in order to make this determination. • Explain why it is easiest to make this measurement with maximum intensity. Question A.2 (1 point) The relationship between wavelength, speed and frequency for a traveling light wave is e-Af Use this to report a determination of the cutoff frequency futott with uncertainty for sodium. Answer: A.1 541 nm. I see this as the longest wavelength the CAN NOT liberate electrons, I am only able to affect changes by about 3 ne to the wavelength w chain this as my uncertainty So, for sodium as the target, the cutoff wavelength is (5413) m It was easiest to measure with maximum intensity because this means the number of photons per time was high s wavelength would be able to liberate electrons. One photon can liberate one electron A.2 Let's use a value for the speed of light from the internet that has a few extra digits of precision use five here) compared to t has three significant figures e-2.9979-10 m/s fac/A to 8f-8( )= 61. fod (5543) 103 Hz where I only kept one significant figure in the uncertainty
