It covers fundamental optical concepts, including the convergence of parallel light rays at the principal focus. Through structured questions and solutions, the material explains why concave mirrors are referred to as converging mirrors and analyzes their practical utility in real-world scenarios such as communication satellite technology and professional dental instrumentation. This resource is designed to align with the NCERT curriculum standards, offering clear diagrams and concise explanations to facilitate student understanding of light reflection principles and their geometric representations, such as poles, focus, and centres of curvature. By evaluating the reflective properties of spherical surfaces, the document serves as an effective tool for classroom study, exam preparation, and reinforcement of key physics principles.",{"@graph":14,"@context":72},[15,34,55],{"@type":16,"itemListElement":17},"BreadcrumbList",[18,23,27,31],{"item":19,"name":20,"@type":21,"position":22},"https://docshare.wps.com","Home","ListItem",1,{"item":24,"name":25,"@type":21,"position":26},"https://docshare.wps.com/document/","Document",2,{"item":28,"name":29,"@type":21,"position":30},"https://docshare.wps.com/document/exam/","Exam",3,{"item":32,"name":10,"@type":21,"position":33},"https://docshare.wps.com/document/physics-class-10th-light-reflection-revision/657092/",4,{"url":32,"name":10,"@type":35,"image":36,"author":41,"headline":10,"publisher":44,"fileFormat":47,"inLanguage":8,"description":12,"dateModified":48,"datePublished":49,"encodingFormat":47,"isAccessibleForFree":50,"interactionStatistic":51},"DigitalDocument",{"url":37,"@type":38,"width":39,"height":40},"https://docshare.wps.com/thumbnails/physics-class-10th-light-reflection-revision/657092.png","ImageObject",300,407,{"name":42,"@type":43},"Danger Angel","Person",{"url":19,"name":45,"@type":46},"DocShare","Organization","application/pdf","2026-10-30","2026-10-26",true,{"@type":52,"interactionType":53,"userInteractionCount":22},"InteractionCounter",{"@type":54},"ViewAction",{"@type":56,"mainEntity":57},"FAQPage",[58,64,68],{"name":59,"@type":60,"acceptedAnswer":61},"Why is a concave mirror also known as a converging mirror?","Question",{"text":62,"@type":63},"A concave mirror is called a converging mirror because it causes all light rays that are parallel to the principal axis to converge at the principal focus after reflection.","Answer",{"name":65,"@type":60,"acceptedAnswer":66},"What shape of metal dish is most efficient for collecting parallel satellite signals?",{"text":67,"@type":63},"A concave metal dish is the most efficient shape because it collects the parallel beam of signals at its focus, where a receiving aerial can be strategically placed.",{"name":69,"@type":60,"acceptedAnswer":70},"Why are concave mirrors used in dental practice?",{"text":71,"@type":63},"Concave mirrors are used by dentists because they can produce magnified images of teeth when the object is placed close to the mirror, allowing for clearer inspection of oral health.","https://schema.org",{"og:url":32,"og:type":74,"og:title":10,"og:site_name":45,"og:description":12},"article",{"robots":76,"canonical":32},"index,follow",{"doc_id":78,"site_id":7},657092,1792973914,{"code":4,"msg":81,"data":82},"success",[83,87,91,94,99,104,109,114,119,122,126],{"id":22,"doc_module":4,"doc_module_name":25,"category_name":84,"show_sort_weight":85,"slug":86},"Story & Novel",90,"story-novel",{"id":26,"doc_module":4,"doc_module_name":25,"category_name":88,"show_sort_weight":89,"slug":90},"Literature",80,"literature",{"id":33,"doc_module":4,"doc_module_name":25,"category_name":29,"show_sort_weight":92,"slug":93},70,"exam",{"id":95,"doc_module":4,"doc_module_name":25,"category_name":96,"show_sort_weight":97,"slug":98},5,"Comic",60,"comic",{"id":100,"doc_module":4,"doc_module_name":25,"category_name":101,"show_sort_weight":102,"slug":103},6,"Technology",50,"technology",{"id":105,"doc_module":4,"doc_module_name":25,"category_name":106,"show_sort_weight":107,"slug":108},7,"Healthcare",40,"healthcare",{"id":110,"doc_module":4,"doc_module_name":25,"category_name":111,"show_sort_weight":112,"slug":113},8,"Research & Report",30,"research-report",{"id":115,"doc_module":4,"doc_module_name":25,"category_name":116,"show_sort_weight":117,"slug":118},9,"Religion & Spirituality",20,"religion-spirituality",{"id":117,"doc_module":4,"doc_module_name":25,"category_name":120,"show_sort_weight":117,"slug":121},"World Cup","world-cup",{"id":123,"doc_module":4,"doc_module_name":25,"category_name":124,"show_sort_weight":123,"slug":125},10,"Lifestyle","lifestyle",{"id":127,"doc_module":4,"doc_module_name":25,"category_name":128,"show_sort_weight":95,"slug":129},19,"General","general",{"code":4,"msg":81,"data":131},{"doc_id":78,"user_id":132,"nickname":42,"user_avatar":133,"doc_module":4,"category_id":33,"category_name":29,"doc_title":10,"doc_description":12,"doc_content":134,"file_id":135,"file_url":136,"file_type":137,"file_size":138,"view_count":22,"is_deleted":4,"is_public":22,"is_downloadable":22,"audit_status":22,"page_count":22,"language":139,"language_code":8,"site_id":7,"html_lang":8,"table_of_contents":140,"faqs":141,"seo_title":142,"seo_description":12,"update_tm":79,"read_time":30},962090769052,"https://ap-avatar.wpscdn.com/davatar_9964176cb1d06d4a9deccf72a44ae3dc","VIDYA BHAVAN, BALIKA VIDYAPEETH  \nSHAKTI UTTHAN ASHRAM, LAKHISARAI, PIN:-811311  \nSUBJECT:-PHYSICS CLASS:-XTH DATE:13/12/XX  \nSUBJECT TEACHER:-MR. NEEL NIRANJAN  \nCHAPTER 2. (LIGHT-REFLECTION) (BASED ON NCERT PATTERN)  \n(REVISION)  \nQuestion 1. Explain with a suitable diagram, how a concave mirror converges a parallel beam of light rays. Mark clearly the pole, focus and centre of curvature of concave mirror in this diagram.  \nSolution :  \nAll the light rays which are parallel to the principal axis of a concave mirror, converge atthe the principal focus (F) after reflection from the mirror. Since a concave mirror converges a parallel beam of light rays, it is also called a converging mirror.  \nQuestion 2. A communications satellite in orbit sends a parallel beam of signals down to earth. If these signals obey the same laws of reflection as light and are to be focussed onto a small receiving aerial, what should be the best shape of the metal ‘dish’used to collect them ?  \nSolution : Concave metal dish: It will collect the parallel beam of satellite signals at its focus where receiving aerial is fixed.  \nQuestion 3. Which type of mirror could be used as a dentist’s mirror ?  \nSolution : Concave mirror.","cbCaicStN1he3zIg","https://ap.wps.com/l/cbCaicStN1he3zIg","pdf",143977,"English","# Light Reflection Revision\n## Principles of Concave Mirrors\n## Practical Applications of Concave Mirrors","[{\"question\":\"Why is a concave mirror also known as a converging mirror?\",\"answer\":\"A concave mirror is called a converging mirror because it causes all light rays that are parallel to the principal axis to converge at the principal focus after reflection.\"},{\"question\":\"What shape of metal dish is most efficient for collecting parallel satellite signals?\",\"answer\":\"A concave metal dish is the most efficient shape because it collects the parallel beam of signals at its focus, where a receiving aerial can be strategically placed.\"},{\"question\":\"Why are concave mirrors used in dental practice?\",\"answer\":\"Concave mirrors are used by dentists because they can produce magnified images of teeth when the object is placed close to the mirror, allowing for clearer inspection of oral health.\"}]","Physics Class 10th - Light Reflection Revision | PDF"]
