Backoreaind Light has atways been a mystery to us. It can exhibit both wave and particle properties: As a wave the frequency of light can be determined by using the universal wave equation; v=f where the v is the speed of light ' 0 ' a constart 3.0107m/s. As at particle the energy of light is quantized as a photon and can be calculated using plenck's constant, h=6.631054+.8 in the equation: E=h. Observe the omission spectra for Hydrogen, record the wavelengths of the major spectral lines and complete the table below: Research in your text book p. 126128 (specifically figures 3.9 and 3.11 and the math link), the energy level changes that result in the visible emission spoctrum for Hydrogen and complete the table below: Tahila 2
