It defines key vocabulary such as light, light source, reflect, refract, prism, ray, normal line, angle of incidence and reflection, and the Law of Reflection. It also explains related concepts including shadow formation, reflective materials, and human eye structures (pupil and retina). The material links ideas through golden vocabulary examples, covers transparency categories (opaque, transparent, translucent), describes color separation via prisms and Newton’s contribution, and summarizes facts about light and refraction.",{"@graph":69,"@context":123},[70,84,106],{"@type":71,"itemListElement":72},"BreadcrumbList",[73,77,79,82],{"item":74,"name":75,"@type":76,"position":8},"https://docshare.wps.com","Home","ListItem",{"item":78,"name":9,"@type":76,"position":14},"https://docshare.wps.com/document/",{"item":80,"name":20,"@type":76,"position":81},"https://docshare.wps.com/document/exam/",3,{"item":83,"name":65,"@type":76,"position":19},"https://docshare.wps.com/document/essential-light-and-shadow-vocabulary/411847/",{"url":83,"name":65,"@type":85,"image":86,"author":91,"headline":65,"publisher":94,"fileFormat":97,"inLanguage":63,"description":67,"dateModified":98,"datePublished":99,"encodingFormat":97,"isAccessibleForFree":100,"interactionStatistic":101},"DigitalDocument",{"url":87,"@type":88,"width":89,"height":90},"https://docshare.wps.com/thumbnails/essential-light-and-shadow-vocabulary/411847.png","ImageObject",300,407,{"name":92,"@type":93},"Stanford","Person",{"url":74,"name":95,"@type":96},"DocShare","Organization","application/pdf","2026-10-30","2026-09-28",true,{"@type":102,"interactionType":103,"userInteractionCount":105},"InteractionCounter",{"@type":104},"ViewAction",11,{"@type":107,"mainEntity":108},"FAQPage",[109,115,119],{"name":110,"@type":111,"acceptedAnswer":112},"What is the Law of Reflection and how is it described using angles?","Question",{"text":113,"@type":114},"The Law of Reflection states that the angle of incidence is always equal to the angle of reflection.

The angle of incidence is always equal to the angle of reflection. The angle of incidence is between the incident ray and the normal line. The angle of reflection is between the reflected ray and the normal line.\u003Cbr>\u003Cbr>\u003Cbr>normal line\u003Cbr> angle of reflection\u003Cbr>\u003Cbr>reflected ray\u003Cbr>shadow An area of darkness where light is blocked. reflective A material which reflects light well. pupil The black part of the eye which lets light in. retina The layer at the back of the eye that takes in light and sends nerve signals to the brain. spectrum A band of colours made by separating the components of light. MAKING LINKS TO PREVIOUS LEARNING\u003Cbr>GOLDEN VOCABULARY pioneer Someone who is among the first to explore somewhere or apply something. Explorers Neil Armstrong was a pioneer as the first man to step onto the moon. opaque Objects that do not allow any light to travel through them, Materials Wood is an example of an opaque material. transparent Objects that allow light to easily travel through them, Materials Glass is an example of a transparent material. translucent Objects that allow some light to travel through, but it is scattered. Materials Frosted glass is an example of a translucent material.\u003Cbr>\u003Cbr>\u003Cbr>Colour When white light passes through a clear glass prism. This means that it changes direction and is spread out as it exits the prism. Often, a spectrum of colours can be seen. Isaac Newton was a pioneer who discovered that the colours\u003Cbr>merge together to make visible light\u003Cbr>Shadows Shadows are always the same shape as the object that has cast them because they are formed when an opaque object blocks the light travelling from the light source. They can be stretched or shortened depending on the angle of the light source. A shadow is larger when the object is closer to the light source as more of the light is blocked.\u003Cbr>\u003Cbr>Parts of the Eye The pupil controls the amount of light that enters the eye, in order to protect theretina. It is an opening at the front of the eye that dilates (gets bigger) when it’s dark and constricts (gets smaller) when it is bright.\u003Cbr>pupil\u003Cbr>\u003Cbr>retina\u003Cbr>\u003Cbr>Facts about Light • It travels faster than sound.\u003Cbr>• Darkness is caused by the absence of light.\u003Cbr>• It travels in a straight line.\u003Cbr>• The moon is not a light source as it reflects light from the Sun.\u003Cbr>• Light can travel through the airless vacuum of space.\u003Cbr>Refraction Objects in water (like a pencil in a glass of water) can appear as if they are bent. This is because when light moves from air to water, it bends. The light beam reflected from the underwater pencil part\u003Cbr>come out of the water in a different direction.\u003Cbr>\u003Cbr>|\n|  |\n\n© Vocabulary Ninja Ltd 2021","cbCailM8o7ADFocA","https://ap.wps.com/l/cbCailM8o7ADFocA","pdf",617933,"English","# Essential Light and Shadow Vocabulary\n## Light and Reflection Terms\n## Shadows and Materials\n## Parts of the Eye\n## Facts about Light\n## Refraction and Color","[{\"question\":\"What is the Law of Reflection and how is it described using angles?\",\"answer\":\"The Law of Reflection states that the angle of incidence is always equal to the angle of reflection.
