Titanium metal requires a photon with a minimum energy of 6.94×10^−19j to emit electrons.
(a)-what is the minimum frequency of light necessary to emit electrons from titanium via the photoelectric effect? express your answer using three significant figures.
(b)- what is the wavelength of this light? express your answer using three significant figures.

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.
