In The Biology of Skin Color, Penn State University anthropologist Dr. Nina Jablonski walks us through the evidence that the different shades of human skin color are evolutionary adaptations to the varying intensity of ultraviolet (UV) radiation in different parts of the world.
Demonstrate reflection of light using a metal spoon and show how curved surfaces differ in the images they reflect. Demonstrate refraction of light as it travels from air into water using a laser pointer and a container of water.
6 gru 2023 · Explain how objects in our surroundings produce different colors through selective reflection or absorption of parts of the visible spectrum.
The manner in which visible light interacts with an object is dependent upon the frequency of the light and the nature of the atoms of the object. In this section of Lesson 2 we will discuss how and why light of certain frequencies can be selectively absorbed, reflected or transmitted.
I can identify examples of light sources and light reflectors. I can explain that light energy can be reflected, transmitted, or absorbed by objects. I can compare transparent, translucent, and opaque objects.
Light reflection occurs when a ray of light bounces off a surface and changes direction. From a detailed definition of ‘reflection of light’ to the different types of reflection and example images, our introductory article tells you everything you need to know about the reflection of light.
