Characteristics of light. • Light is an electromagnetic wave. As shown below, an electromagnetic wave is a transverse wave consisting of mutually perpendicular oscillating electric and magnetic fields. Electromagnetic waves are ultimately produced by an accelerating charge. A changing electric field produces a changing magnetic field which in ...

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.
of the light. Shiny objects _____ a lot of light. Opaque objects _____ and _____ light. 6. Why do shadows form? 7. Give an example of a transparent object and a translucent object. 8. True or False: Translucent objects let some light pass through, but only certain colours. 9. True or False: Light moves faster through water than through air. 10.
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.
The properties of light are an important part of a physics and physical science curriculum. You make observations pertaining to the two properties of reflection and refraction almost daily. By using the tutorials, you can see the physics behind several common phenomena. Save a copy of the following questions on your computer.
glass on to a sheet of paper and burn a hole in it. You have added so much energy to the paper that its temperature rises to the point where it ignites. 3. There are certain situations where describing light as rays works well (for example, lenses) and there are other situations where describing light as waves works well (for example, diffraction).
