He-ne lasers are often used in physics demonstrations. they produce light of wavelength 633nm and a power of 0.650mw spread over a cylindrical beam 1.35mm in diameter (although these quantities can vary).part awhat is the intensity of this laser beam? i=/m^2part bwhat is the maximum value of the electric field? emax=/mpart cwhat is the maximum value of the magnetic field? bmax= d

1) when you rub your hands together quickly, the kinetic energy is converted to mechanical energy.2) thermal energy from the sun travels to earth as infrared waves.3) energy is transferred through the matter of space by electromagnetic waves. 4) when a match is burned, chemical potential energy is converted to thermal and radiant energy. 5) seismicwaves are caused by back and forth movement , or vibration, of an object. 6) mechanicalenergy in an engine changes thermal energy into kinetic energy to make a car move.
