Summary:
Light is an electromagnetic wave that comes in many forms. Visible light is a small portion of light that makes up color. There are other types of light, such as infrared light which creates light based on the heat of objects. Infrared light has longer wavelengths, therefore making it impossible to see by the naked eye. Light can be reflected, refracted, or transmitted. Reflection refers to when light bounces off an object without being completely absorbed. Refraction refers to when light goes through mediums of varying density, therefore changing direction (bending light). Finally, transmission refers to when light completely passes through an object, such as glass.
SP4 - Analyzing Data:
This week I analyzed data when investigating how the moon and its phases were influenced by light. Upon investigating it, I was given an animation to view in order to understand why the moon changes throughout each month. Through that animation, I found out that the moon changed phases due to its position relative to the sun and earth. For example, the new moon phase displays a completely dark moon due to the fact that the moon is between the earth and the sun, meaning that no light hits the side of the moon that faces the earth, creating a dark moon. To display this information, I sketched out each phase of the moon along with the lunar days (the duration of the phase)
