Waves G12

  3. 3. SAMPLE ONLY SAMPLE ONLY SAMPLE ONLY For FULL presentation click HERE >> www.warnescience.net Double slit interference Two sets of coherent waves will interfere with each other producing INTERFERANCE patterns. This can be seen by allowing a set of waves to pass through a double slit. Nodal lines – destructive interference.

A thin rectangular piece of glass is painted with black paint, and a thin single slit is made on the paint with a razor blade.  White Light A beam of white light is shone through the slit.  Observation 1) A broad …………………….. of bright white light is observed. 2) This is flanked by alternate spectral ……………….. and black fringes.  What factors would affect the amount of diffraction?? How??

Find the position of the first dark band formed on the screen when red light of wavelength 690 nm is passed through a slit of width 6.0 m. 2. Compare this with the position of the first order dark band when blue light of wavelength 460 nm is used. 6.60o 4.40o
