Light is shone on a diffraction grating with d= 1.00*10^-6 m. The second-order (m=2) maximum occurs at an angle of 74.6 degrees. What is the wavelength of the light IN NANOMETERS? nm

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.

Because its reliable.   there is no pollution  the chances of a radiation leak is low
