The frame holds all the<br \/>\nexperiment parts and allows the user to slide the parts<br \/>\nalong easily for experiments of transfer over distances. The<br \/>\nControl Box contains the electrical controls and displays of<br \/>\nthe measured readings.<\/span><\/li>\n<li><span class=\"fontstyle0\">The heat source uses a variable low-voltage electric<br \/>\nheater on a flat plate, creating a black body heat source<br \/>\nof variable temperature. A thermocouple measures<br \/>\nthe heat source temperature. A moveable thermopile<br \/>\nmeasures the heat radiation from the heat source at<br \/>\nvarying distances. TecQuipment include plates with<br \/>\ndifferent apertures, surface finishes and thermocouples.<br \/>\nThey allow extra experiments that show how surface finish<br \/>\naffects emissivity and absorptivity, and the area factor for<br \/>\nheat transfer<\/span><\/li>\n<li><span class=\"fontstyle0\">The light source uses a low voltage lamp inside an<br \/>\nintegrating sphere to create a diffuse light. Students can<br \/>\nrotate the light source through a range of angles (shown<br \/>\non a protractor scale) for experiments in light direction. A<br \/>\nmoveable Lux Meter measures the light radiation from the<br \/>\nlight source at varying distances. TecQuipment includes<br \/>\ndifferent optical filters (coloured, neutral density and<br \/>\ninfra-red block). They allow extra experiments that show<br \/>\nhow optical filters affect light transfer.<\/span><\/li>\n<li><span class=\"fontstyle0\">A clear, multiline digital display on the Control Box shows<br \/>\ntemperatures and light or heat radiation<\/span><\/li>\n<\/ul>\n<p><em><span style=\"text-decoration: underline;\">Learning Outcomes:<\/span><\/em><\/p>\n<ul>\n<li>Heat\n<ul>\n<li><span class=\"fontstyle0\">Inverse square law (or Lambert\u2019s distance law\/area law) \u2013 showing radiation is inversely proportional to distance squared<\/span><\/li>\n<li><span class=\"fontstyle0\">Stefan-Boltzmann law \u2013 showing the relationship between radiation and source temperature<\/span><\/li>\n<li><span class=\"fontstyle0\">Kirchhoff\u2019s law \u2013 showing that a body with good emissivity also has good absorptivity<\/span><\/li>\n<li><span class=\"fontstyle0\">Area factor \u2013showing that radiation transfer depends on the exposed area of the radiant source<\/span><\/li>\n<\/ul>\n<\/li>\n<li>Light:\n<ul>\n<li><span class=\"fontstyle0\">Inverse square law (or Lambert\u2019s distance law\/area law) \u2013 showing radiation is inversely proportional to distance squared<\/span><\/li>\n<li><span class=\"fontstyle0\">Lambert\u2019s direction law (or cosine law) \u2013 showing that radiation is proportional to the cosine of the angle between the emitter and the receiver<\/span><\/li>\n<li><span class=\"fontstyle0\">Transmittance and absorbance \u2013 showing that optical filters can reduce light intensity<\/span><\/li>\n<\/ul>\n<\/li>\n<\/ul>\n","protected":false},"excerpt":{"rendered":"<p>Product Code: TD1003<\/p>\n","protected":false},"featured_media":3193,"template":"","meta":[],"product_cat":[31,884],"product_tag":[],"_links":{"self":[{"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/product\/3417"}],"collection":[{"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/product"}],"about":[{"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/types\/product"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/media\/3193"}],"wp:attachment":[{"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/media?parent=3417"}],"wp:term":[{"taxonomy":"product_cat","embeddable":true,"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/product_cat?post=3417"},{"taxonomy":"product_tag","embeddable":true,"href":"https:\/\/dbm.com.vn\/en\/wp-json\/wp\/v2\/product_tag?post=3417"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
