Problem 6: A soap bubble is 105 nm thick and illuminated by white light incident perpendicular to its surface. What is the longest wavelength in nm which is constructively reflected, assuming soap has the same index of refraction as water (n = 1.33)? 1 = The figure shows the electron energy-level diagram during a collision between a helium atom and a neon atom, which occurs in helium-neon Colision transfers energy (HeNe) lasers. A population of electrons is created in the metastable state of heavy Matastable the neon atoms via collisions with excited helium atoms. This excess of electrons in an excited state is called "population inversion" 20.61 QV 20.66 ov Ground state Neon theexpertta.com Part (a) What is the energy, in electron volts, of the photon emitted when an electron in neon goes from its metastable state to the one immediately below? E = Part (b) What is the wavelength of this radiation in nanometers? ^ = Part (c) What wavelength, in nanometers, is emitted when the electron in neon makes a direct transition, from the metastable state, to its ground state? 7= Problem 14: In a diffraction experiment, a coherent light source illuminates slits in a diffraction grating, and the resulting pattern is projected on a screen that is separated from the barrier by a distance which is very large as compared to the wavelength of the light source and to the slit width and slit separation of the grating. A student made a sketch of the positions of the bright lines. Three iterations of the experiment employed three different light sources, and each had a different wavelength. Initially all of the sketches were made with a plain pencil, and only later the color was added. -50.0 -40.0 -30.0 -20.0 -10.0 0.0 10.0 20.0 30.0 40.0 50.0 50.0 -4 0.0 -20.0 -10.0 0.0 10.0 20.0 30.0 40.0 50.0 y (cm) y (cm) -50.0 -40.0 -30.0 -20.0 -10.0 0.0 10.0 20.0 30.0 40.0 50.0 y (cm) Are the color choices consistent with the other plot features? The diagrams were colored correctly because violet light has the longest wavelength and red light has the shortest wavelength. C The diagrams were colored incorrectly because red light has the longest wavelength and volet light has the shortest wavelength C The diagrams were colored incorrectly because green light has the longest wavelength. The diagrams were colored incorrectly because violet light has the longest wavelength and red light has the shortest wavelength. C The diagrams were colored correctly because red light has the longest wavelength and volet light has the shortest wavelength. The diagrams were colored incorrectly because green light has the shortest wavelength
