Apr 10, 2022 · Example 5.1. 1 5.1. 1: Deriving and Using the Wave Equation. The equation for the relationship between the speed and other characteristics of a wave can be derived from our basic understanding of motion. The average speed of anything that is moving is: average speed = distance × time average speed = distance × time.

Light refracts whenever it travels at an angle into a substance with a different refractive index (optical density4). This change of direction is caused by a change in speed. For example, when light travels from air into water, it slows down, causing it to continue to travel at a different angle or direction. How much does light bend? The amount of...
A lens5 is simply a curved block of glass or plastic6. There are two kinds of lens. A biconvex7lens is thicker at the middle than it is at the edges. This is the kind of lens used for a magnifying glass. Parallel rays of light can be focused in to a focal point. A biconvex lens is called a converging lens. A biconcave lens curves is thinner at the ...
Isaac Newton performed a famous experiment using a triangular block of glass called a prism. He used sunlight shining in through his window to create a spectrum of colours on the opposite side of his room. This experiment showed that white light is actually made of all the colours of the rainbow8. These seven colours are remembered by the acronym R...
A rainbow is caused because each colour refracts at slightly different angles as it enters, reflects off the inside and then leaves each tiny drop of rain. A rainbow is easy to create using a spray bottle and the sunshine. The centre of the circle of the rainbow will always be the shadow11of your head on the ground. The secondary rainbow that can s...
Jun 7, 2023 · Reflection and refraction can work together — often with awesome results. Consider the bending of the sun’s light as it passes through Earth’s atmosphere at a low angle. This tends to happen at sunrise or sunset. Sunlight’s bending, or refracting, paints clouds near the horizon in an array of red and orange hues.
Strategy: The speed of light in a material, v, can be calculated from the index of refraction n of the material using the equation n = c / v. Solution. The equation for index of refraction (Equation 25.3.3) can be rearranged to determine v. v = c n.
The same two conditions that are necessary for bending the path of the line of students are also necessary for bending the direction of a light ray. Light refracts at a boundary because of a change in speed. There is a distinct cause-effect relationship. The change in speed is the cause and the change in direction (refraction) is the effect.

Jul 7, 2021 · View Description. Light and matter interact with each other. Matter can absorb light (take it in); emit light (give it off); transmit light (allow it to pass through); reflect light (cause it to bounce off); and refract light (cause it to change speed and direction).
