\nL\u2019objectiu d\u2019aquesta experi\u00e8ncia \u00e9s determinar la constant de Planck (h) utilitzant d\u00edodes emissors de llum (LED). En aquests dispositius l\u2019emissi\u00f3 de llum s\u2019aconsegueix quan un corrent el\u00e8ctric passa a trav\u00e9s de la uni\u00f3 entre dos materials semiconductors. En aquesta uni\u00f3 les c\u00e0rregues el\u00e8ctriques poden recombinar-se per donar lloc a fotons que formen la llum.
\nPer aconseguir aquest objectiu, primerament els estudiants han de determinar la longitud d\u2019ona (\u03bb) de quatre leds (vermell, taronja, verd i blau) utilitzant una xarxa de difracci\u00f3 i una webcam. Conegut el valor de la longitud d\u2019ona, els estudiants calculen la freq\u00fc\u00e8ncia (f) del LED emprat.
\nA continuaci\u00f3, i a trav\u00e9s d\u2019un circuit que permet mesurar la difer\u00e8ncia de potencial al que est\u00e0 sotm\u00e8s el LED i la intensitat que circula per ell, els alumnes determinen el voltatge llindar perqu\u00e8 el LED comenci a emetre llum. Considerant que tota l\u2019energia el\u00e8ctrica es transforma en llum en el d\u00edode, i realitzant un balan\u00e7 energ\u00e8tic, s\u2019obt\u00e9 la constant de Planck.
\nEl fet d\u2019utilitzar materials quotidians amb els que tothom hi est\u00e0 perfectament familiaritzat com s\u00f3n una webcam o un LED contribueix a despertar l\u2019inter\u00e8s de l\u2019alumnat a l\u2019hora que ho fa tot plegat molt m\u00e9s proper.[\/et_pb_text][\/et_pb_column][\/et_pb_row][et_pb_row _builder_version=”4.5.1″ _module_preset=”default” background_color=”#e1e1e1″][et_pb_column type=”4_4″ _builder_version=”4.5.1″ _module_preset=”default” background_color=”#e1e1e1″][et_pb_image src=”https:\/\/outreach-wp.ixole.es\/wp-content\/uploads\/2020\/08\/perez-1.jpg” title_text=”perez” url=”https:\/\/outreach-wp.ixole.es\/wp-content\/uploads\/2020\/08\/perez-1.jpg” align=”center” force_fullwidth=”on” _builder_version=”4.5.7″ _module_preset=”default”][\/et_pb_image][et_pb_post_nav _builder_version=”4.5.1″ _module_preset=”default” title_font=”|600|||||||” title_text_color=”#918050″][\/et_pb_post_nav][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=”1_3,1_3,1_3″ use_custom_gutter=”on” gutter_width=”1″ make_equal=”on” admin_label=”row” module_class=” et_pb_row_fullwidth” _builder_version=”4.5.1″ background_size=”initial” background_position=”top_left” background_repeat=”repeat” width=”100%” width_tablet=”100%” width_phone=”” width_last_edited=”on|desktop” max_width=”100%” max_width_tablet=”100%” max_width_phone=”” max_width_last_edited=”on|desktop” custom_padding=”0px||0px|” make_fullwidth=”on” use_custom_width=”off” width_unit=”on”][et_pb_column type=”1_3″ _builder_version=”4.5.1″ background_color=”#e1e1e1″ custom_padding=”|45px||45px|false|false” custom_padding__hover=”|||”][\/et_pb_column][et_pb_column type=”1_3″ _builder_version=”4.5.1″ background_color=”#e1e1e1″ custom_padding=”|45px||45px|false|false” custom_padding__hover=”|||”][\/et_pb_column][et_pb_column type=”1_3″ _builder_version=”4.5.1″ background_color=”#e1e1e1″ custom_padding=”|45px||45px|false|false” custom_padding__hover=”|||”][et_pb_button button_url=”@ET-DC@eyJkeW5hbWljIjp0cnVlLCJjb250ZW50IjoicG9zdF9saW5rX3VybF9wb3N0Iiwic2V0dGluZ3MiOnsicG9zdF9pZCI6IjYzNjUifX0=@” button_text=”Tornar als projectes” button_alignment=”left” admin_label=”Bot\u00f3n Dorado” module_id=”botons” module_class=”botons” _builder_version=”4.5.7″ _dynamic_attributes=”button_url” custom_button=”on” button_text_color=”#918050″ button_border_color=”#918050″ button_icon_color=”#918050″ button_on_hover=”off” hover_enabled=”0″ custom_css_main_element=”margin-top: 10px;” custom_css_after=” margin-left: 0px !important;” button_text_color_hover=”#918050″ button_border_color_hover=”#918050″ button_border_radius_hover=”0″ button_letter_spacing_hover=”0″ saved_tabs=”all” button_text_size__hover_enabled=”off” button_one_text_size__hover_enabled=”off” button_two_text_size__hover_enabled=”off” button_text_color__hover_enabled=”on” button_text_color__hover=”#918050″ button_one_text_color__hover_enabled=”off” button_two_text_color__hover_enabled=”off” button_border_width__hover_enabled=”off” button_one_border_width__hover_enabled=”off” button_two_border_width__hover_enabled=”off” button_border_color__hover_enabled=”on” button_border_color__hover=”#918050″ button_one_border_color__hover_enabled=”off” button_two_border_color__hover_enabled=”off” button_border_radius__hover_enabled=”on” button_border_radius__hover=”0″ button_one_border_radius__hover_enabled=”off” button_two_border_radius__hover_enabled=”off” button_letter_spacing__hover_enabled=”on” button_letter_spacing__hover=”0″ button_one_letter_spacing__hover_enabled=”off” button_two_letter_spacing__hover_enabled=”off” button_bg_color__hover_enabled=”off” button_one_bg_color__hover_enabled=”off” button_two_bg_color__hover_enabled=”off”][\/et_pb_button][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":"
