Trivia Question Where is the largest laser system in the world? (a) Andrews Air Force Base (b) USS Enterprise (c) Area 51, located in ???? (d) Sandia National Lab, New Mexico (e) Lawrence Livermore National Lab, California Trivia Question Where is the largest laser system in the world? (e) Lawrence Livermore National Lab, California National Ignition Facility (NIF) – is a quest for clean fusion energy. Pellets of hydrogen of fused using intense laser pulses. July 5th, 2012: 192 laser beams delivered 1.85MJ and 500 trillion watts of power (short time period). 1000 times more power than used by US at any instant of time.

Trivia Question In addition to being famous for developing Maxwell’s Equations for electromagnetic theory, James Clerk Maxwell is also famous for discoveries in which of the following topics? (a) Relativity (b) Nuclear Physics (c) The Telephone (d) The internet (e) Human color vision Trivia Question In addition to being famous for developing Maxwell’s Equations for electromagnetic theory, James Clerk Maxwell is also famous for discoveries in which of the following topics? (a) (b) (c) (d) (e) Human color vision Where are we in our ‘road map’ of Optics? The ‘amplitude’ of the wave in optics will be related to the ‘magnitude’ of electric and magnetic fields. Electric fields and magnetic fields will be treated as vectors, not scalars.

Similar principle can be used for “touch screens” of tablets, smart phones, etc. Parallel plate capacitor Note: it is ASSUMED that charge is equal and opposite on the two plates The positive charges on one plate are attracted to the negative charges on another. If we let the charges move (ie. current), we could power (for example) a light bulb. In that case we would convert STORED energy of electric field (from separated charges) to electrical power for light bulb.
