1. Overview

This document reviews a JavaScript Simulation Applet (HTML5) titled "Where is the Fish under Water." The applet, part of the Open Educational Resources / Open Source Physics @ Singapore project, focuses on demonstrating light refraction and its effect on observed object position, using a "fish under water" scenario. It allows users to manipulate various parameters, such as fish and eye position and refractive indices, to observe changes in the line of sight and image formation.

2. Main Themes and Ideas

Quiz Answer Key

1. The simulation demonstrates the principle of light refraction, specifically how light bends when it passes from one medium (water) to another (air), causing the fish to appear in a different location than its actual position. The bending of light creates an optical illusion.
2. The parameters n1 and n2 are adjustable via sliders. These likely represent the refractive indices of the two mediums (air and water), and changing them alters the degree of refraction and therefore the apparent position of the image of the fish.
3. The simulation allows users to drag the fish to change its submerged location. Similarly, the eyes representing the observer's viewpoint, can also be dragged to change their position.
4. When the position of the fish or the eyes is changed, the line of sight adjusts to reflect the new angle of observation, and the image of the fish changes based on the amount of refraction occurring at the water-air interface. This models the effect of changing perspective on observed position.
5. The Play/Pause button starts and stops the simulation (if it involves animation or movement), the Step button advances the simulation by a single increment (if applicable), and the Reset button returns the simulation to its initial default state. This allows for interactive control and experimentation.
6. Examples include "Bus in Garage Relativity Length Lorentz Transformation JavaScript Simulation Applet HTML 5", "🚚Drag the Monster Truck JavaScript Simulation Applet HTML5," or any other simulation listed after "Graphing Lines by Phet".
7. The contents are licensed under the Creative Commons Attribution-Share Alike 4.0 Singapore License, indicating that the material can be shared and adapted as long as attribution is given and any derivative works are licensed under the same terms. Commercial use requires licensing the EasyJavaScriptSimulations Library directly from the University of Murcia.
8. The intended purpose of the simulation is educational, specifically to help students visualize and understand the concept of light refraction and how it affects our perception of objects underwater.
9. The creators/contributors listed are Fu-Kwun Hwang, Fremont Teng, and lookang.
10. A teacher could use this simulation to demonstrate how light bends when it travels from water to air, leading to a distorted perception of the fish's actual location, thereby engaging the students with a real-world application of physics. It would be useful to explore student misconceptions about how light travels.
