PPT-Diffraction of Water Waves

Pg 459 461 Properties of Waves In order to study the properties of waves a ripple tank is used A shallow glassbottomed tank on left 2cm of water is added Light from a source above the tank passes through the water and illuminates a screen on the table below. Huygen’s Principle. Any wave (including electromagnetic waves) is able to propagate because the wave . here . affects nearby points . there. In a sense, the wave is the source for more of the wave. Has wave properties.. Can diffract.. Can constructively or destructively interfere. .. Coherent Light. A beam of light that has the same frequency, wavelength, phase, and direction is called . coherent. Physics 2415 Lecture 38. Michael Fowler, . UVa. Today’s Topics. Multi-slit interference.
