2.A light source has energy distributed in the range of the wavelength from 1 = 600 to 600.018 nmand contains many fine spectral lines. The minimum interval of two fine spectral lines is Al =6 x 10-4nm. In order to fully analyze this light source using a spectrometer with a fixed Fabry-Perot (FP) etalon (as shown in Slide 13 of Lecture 12), ask:a) What is the maximum separation distance of this FP etalon (L)?b) If two FP etalons have the same separation distance, but different reflectance R1 = 0.89 andR2 = 0.92, respectively, please compute resolving power of two FP etalons and determine whichone can be used in this application.

Given: ∆λ=6×10-4nm, λ=600-600.018nm (a) The maximum separation of the FP etalon is given by :…

This question relates to the practicality of searching for intelligent life in other solar systems by detecting their radio broadcasts (or aliens find us from ours). The closest stars are 4 light years away from us. How far away must you be from a 460 kHz radio station with power 50.0 kW for there to be only one photon per second per square meter? Assume that the photons spread out spherically. The area of a sphere is 4??24πr2. b) How many lightyears away is this?
Suppose you measured a spectrum of a laser source which peaks at a wavelength of 810 nm. Find the energy (in eV) associated with this wavelength. From the LED spectrum data you want to find the width of the peak at half the height of the peak. The wavelengths at which the intensity is half of its peak value are 630 nm and 666 nm respectively. Using these wavelengths determine the width of the peak in units of energy (eV). From the N2 spectrum data you noted two prominent peaks at wavelengths 330 nm and 350 nm. Determine the energy associated with each peak. The larger energy represents the energy difference between the vibrational ground states of two molecular orbitals (denoted by C’IIu and B³IIL). The smaller one represents the energy difference between the vibrational ground state of the C'II, orbital and first excited vibrational state of B³II.. The difference between these energies represents the energy difference between the ground and first excited vibrational levels. Find this…

Although electron microscopy is the preferred technique for measuring high resolution scientific images, scanning probe microscopy can utilize the smallness of wavelengths to create an image of particles not visible through regular microscopes. In general, the wavelength of the scanning light must be at least as small as the item being scanned in order to detect the presence of the item.
