- Please I want a correct and clear solution to this question. The solution must be clear and handwritten. Course name: Lasers and its Applications 412PHYSDetermine the probability that a photon is detected at the location of the first minimum of a 3-slit grating if the thrid slit is closed. You can assume that the magnitude of the probability amplitude due to each slit is r. (Hint: Start by showing how the complex amplitudes from each slit add up to zero at the first minimum. What is the resulting amplitude if the first amplitude is eliminated?)I need the answer as soon as possible
- Use the worked example above to help you solve this problem. A sodium surface is illuminated with light of wavelength 0.329 µm. The work function for sodium is 2.46 eV.Show that a 30,000-line-per-centimeter grating will notproduce a maximum for visible light. (b) What is the longestwavelength for which it does produce a first-order maximum?(c) What is the greatest number of lines per centimeter adiffraction grating can have and produce a complete secondorder spectrum for visible light?describe in sufficient detail how the photodiode array monitors the absorbance (A) of a spectrum of wavelengths simultaneously.
- A Fabry-Perot device contains two parallel part-reflective surfaces, each with a power reflection coefficient R = 0.9, separated by an air gap of 0.05 mm.
