Founded in 2002 by Nobel Laureate Carl Wieman, the PhET Interactive Simulations project at the University of Colorado Boulder creates free interactive math and science simulations. PhET sims are based on extensive education <a {{0}}>research</a> and engage students through an intuitive, game-like environment where students learn through exploration and discovery.
In this demo, students closely observe some basic properties and behaviors of waves, including propagation, reflection, refraction, and diffraction, using a ripple tank in the classroom. Then students use a wave simulator. Finally, students look for real-world, large-scale examples of wave reflection, interference, and refraction around the globe.
19 Δεκ 2021 · Figure 5.6: Wave refraction diagram. Wave energy converges in the case of convex depth contours (as seen from the sea) and diverges in the case of concave depth contours. The effect of refraction on the wave height in the present example is to reduce the increase in wave height due to shoaling.
The worksheets will show students how to break apart the anatomy of wave and calculate the key measures that differentiate waves from each other. Students will explore the key vocabulary that is associated with light and sound waves. They will explore how light waves bounce and refraction naturally and through a series of different lenses.
Refraction of waves involves a change in the direction of waves as they pass from one medium to another. Refraction, or the bending of the path of the waves, is accompanied by a change in speed and wavelength of the waves.
Explore bending of light between two media with different indices of refraction. See how changing from air to water to glass changes the bending angle. Play with prisms of different shapes and make rainbows.
Now let’s look at some ray diagrams showing refraction. To make a refraction ray diagram, draw a solid line to show the boundary between the two materials (water and air in this case). Arrows are used to represent the incident and refracted light rays. The normal is a dashed line drawn perpendicular to the boundary between the surfaces. It ...
