Light rays obey two laws viz. the incident ray, normal and reflected ray lies in the same point in the same plane and the angle of incidence of always equal to the angle of reflection. hmm • When light passes through a denser medium, it gets refracted. The glass slab activity is a simple method to study the laws of light and understand the concept of refraction.","styleRuns":[{"startIndex":0,"length":363,"styleRunExtensions":{"styleRunColorMapExtension":{"colorMap":[{"key":"USER_INTERFACE_THEME_DARK","value":4294967295},{"key":"USER_INTERFACE_THEME_LIGHT","value":4279440147}]}},"fontFamilyName":"Roboto"}]},"headerRuns":[{"startIndex":0,"length":363,"headerMapping":"ATTRIBUTED_STRING_HEADER_MAPPING_UNSPECIFIED"}]}},{"itemSectionRenderer":{"contents":[{"continuationItemRenderer":{"trigger":"CONTINUATION_TRIGGER_ON_ITEM_SHOWN","continuationEndpoint":{"clickTrackingParams":"CKwBELsvGAIiEwjD-Jm8xOeJAxU7a3oFHcZfM6k=","commandMetadata":{"webCommandMetadata":{"sendPost":true,"apiUrl":"/youtubei/v1/next"}},"continuationCommand":{"token":"Eg0SC0E1TzkydHlLWGxrGAYyJSIRIgtBNU85MnR5S1hsazAAeAJCEGNvbW1lbnRzLXNlY3Rpb24%3D","request":"CONTINUATION_REQUEST_TYPE_WATCH_NEXT"}}}}],"trackingParams":"CKwBELsvGAIiEwjD-Jm8xOeJAxU7a3oFHcZfM6k=","sectionIdentifier":"comment-item-section","targetId":"comments-section"}}],"trackingParams":"CKsBELovIhMIw_iZvMTniQMVO2t6BR3GXzOp"}},"secondaryResults":{"secondaryResults":{"results":[{"compactVideoRenderer":{"videoId":"eAdNy8cRH94","thumbnail":{"thumbnails":[{"url":"https://i.ytimg.com/vi/eAdNy8cRH94/hqdefault.jpg?sqp=-oaymwE8CKgBEF5IWvKriqkDLwgBFQAAAAAYASUAAMhCPQCAokN4AfABAfgB_gmAAtAFigIMCAAQARhyIFUoOzAP
