INTERFERE NCE THIAN NUN MAWI PERIOD 3

OBJECTIVES  Describe how light waves interfere with each other to produce bright and dark fringes.  Identify the conditions required for interference to occur.  Predict the location of inference fringes using the equation for double-slit inference.

COMBINING LIGHT WAVES  Interference take place only between waves with the same wavelength. A light source that has a single wavelength is called Monochromatic.  In constructive interference, component waves combine to from a resultant wave the same wavelength but with an amplitude that is greater than the either the individual component waves.  In the case of destructive interference, the resultant amplitude is less than the amplitude of the larger component wave.
