New situation: A new grating of unknown number of lines per centimeter is used. A green light of wavelength of 520.0 nm passes the new grating. On the screen at a distance of L = 2.00 m from the grating. the distance between the 2nd order maximum and center of the central maximum is 2.204 m - Learning Goal: Grating (also called diffraction grating) A diffraction grating has a large number of very narrow slits that are very closely separated. A Part F - New situation: for the green light, find the angle of the 2nd order maximum (Bright fringe) relative to the incident beam. typical grating quotes the number of lines per centimeter (or per millimeter, or per inch). A diffraction grating produces very sharp bright fringes or spots which are called maxima. Keep 2 digits after the decimal point. (Figure 1) Suppose you have a grating with 8900 lines per cm, fom = 0.01 m. You send a beam of white ight through it and observe the interference pattern on a screen at a distance of L = 2:00 m from the grating- Ozgreen The wavelength of white light is between 380.0 nm (violaet) and 760.0 nm (red), 1nm = 109 m. 27.56 Submit Previous Anewere Request Answer * Incorrect; Try Again; 4 attempts remaining Part G - New situation: What is the separation drew between two adjacent lines on the new grating? The unit is pan = 10 m. Keep 3 digits after the decimal point.
