The wavelength of visible light is very small. For example, waves of orange light have a length of only 0.0000006 meter. Because the wavelength of light is so small, scientists use nanometers. One nanometer (nm) is one billionth of a meter (0.000000001 m). Figure 10.5 shows the size of a light wave relative to other small things.
S4-5)PS4.A: Wave PropertiesThe wavelength and frequency of a wave are related to one another by the speed of travel of the wave, which depends on the type of wave and the medium. through wh. Information can be digitized (e.g., a picture stored as the values of an array of pixels); in this form, it can be stored.
ratio of the speed of light in a vacuum to the speed of light in the medium. n = cv To determine the speed of light in a particular medi-um, divide the speed of light by the index of refrac-tion. v v v = = c n = 2.0 × 108 m/s 3.0 × 108 m/s 1.5 9. A The speed of light within a medium is inversely pro-portional to its index of refraction. The ...
In this module you will learn about the nature and properties of light in the following lessons: Lesson 1 – The Nature of Light Lesson 2 – Reflection and Mirrors Lesson 3 – Refraction and Lenses Lesson 4 – Colors, Interference and Polarization. What you are expected to learn.
Duffy_EP_2012_ch23. Light can be described by several different models. In Chapters 23 and 24, we will make use of a relatively simple model of light known as the ray model. The ray model will help us to understand how light interacts with mirrors and lenses, and help us understand how the reflection of light can produce beautiful photographs ...
The document discusses several key properties of light including reflection, refraction, dispersion, interference, and diffraction. Reflection causes light to bounce off surfaces at varying angles. Refraction causes light to bend when passing between materials of different densities, as seen in mirages and rainbows. Dispersion separates white light into a spectrum of colors using prisms ...
