The . particle nature of light was the basis for ray (geometric) . optics. Light waves interfere with each other much like mechanical waves do. Two pulses travelling in opposite directions will pass through each other unaffected. While passing, the displacement is simply the sum of the individual displacements. CP 514. SUPERPOSITION OF WAVES. Pg. 459 - 461. Properties of Waves. In order to study the properties of waves, a ripple tank is used. A shallow, glass-bottomed 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. Section 9.1. Key Terms. Interference. Principle of Superposition. Constructive Interference.

With a few simple sketches, explain refraction in terms of the gradual change in the speed of a wavefront as it passes through an interface at an angle to the normal. . 1-d and 2-d waves.

Science Journal Entry 34. Compare and contrast transverse waves, longitudinal waves, and surface waves.. Review. There are three types of waves: transverse, longitudinal, and surface waves.. A transverse wave causes the medium to vibrate at right angles to the direction of the wave. Longitudinal waves (also called compressional waves) cause the medium to move parallel to the direction of the wave.. this week and have started doing the first Mastering Physics assignment. . due on Friday. . !! .
