\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=\u00bb4.5.1″ _module_preset=\u00bbdefault\u00bb background_color=\u00bb#e1e1e1″][et_pb_column type=\u00bb4_4″ _builder_version=\u00bb4.5.1″ _module_preset=\u00bbdefault\u00bb background_color=\u00bb#e1e1e1″][et_pb_image src=\u00bbhttps:\/\/outreach-wp.ixole.es\/wp-content\/uploads\/2020\/08\/perez-1.jpg\u00bb title_text=\u00bbperez\u00bb url=\u00bbhttps:\/\/outreach-wp.ixole.es\/wp-content\/uploads\/2020\/08\/perez-1.jpg\u00bb align=\u00bbcenter\u00bb force_fullwidth=\u00bbon\u00bb _builder_version=\u00bb4.5.7″ _module_preset=\u00bbdefault\u00bb][\/et_pb_image][et_pb_post_nav _builder_version=\u00bb4.5.1″ _module_preset=\u00bbdefault\u00bb title_font=\u00bb|600|||||||\u00bb title_text_color=\u00bb#918050″][\/et_pb_post_nav][\/et_pb_column][\/et_pb_row][et_pb_row column_structure=\u00bb1_3,1_3,1_3″ use_custom_gutter=\u00bbon\u00bb gutter_width=\u00bb1″ make_equal=\u00bbon\u00bb admin_label=\u00bbrow\u00bb module_class=\u00bb et_pb_row_fullwidth\u00bb _builder_version=\u00bb4.5.1″ background_size=\u00bbinitial\u00bb background_position=\u00bbtop_left\u00bb background_repeat=\u00bbrepeat\u00bb width=\u00bb100%\u00bb width_tablet=\u00bb100%\u00bb width_phone=\u00bb\u00bb width_last_edited=\u00bbon|desktop\u00bb max_width=\u00bb100%\u00bb max_width_tablet=\u00bb100%\u00bb max_width_phone=\u00bb\u00bb max_width_last_edited=\u00bbon|desktop\u00bb custom_padding=\u00bb0px||0px|\u00bb make_fullwidth=\u00bbon\u00bb use_custom_width=\u00bboff\u00bb width_unit=\u00bbon\u00bb][et_pb_column type=\u00bb1_3″ _builder_version=\u00bb4.5.1″ background_color=\u00bb#e1e1e1″ custom_padding=\u00bb|45px||45px|false|false\u00bb custom_padding__hover=\u00bb|||\u00bb][\/et_pb_column][et_pb_column type=\u00bb1_3″ _builder_version=\u00bb4.5.1″ background_color=\u00bb#e1e1e1″ custom_padding=\u00bb|45px||45px|false|false\u00bb custom_padding__hover=\u00bb|||\u00bb][\/et_pb_column][et_pb_column type=\u00bb1_3″ _builder_version=\u00bb4.5.1″ background_color=\u00bb#e1e1e1″ custom_padding=\u00bb|45px||45px|false|false\u00bb custom_padding__hover=\u00bb|||\u00bb][et_pb_button button_url=\u00bb@ET-DC@eyJkeW5hbWljIjp0cnVlLCJjb250ZW50IjoicG9zdF9saW5rX3VybF9wb3N0Iiwic2V0dGluZ3MiOnsicG9zdF9pZCI6IjYzNjUifX0=@\u00bb button_text=\u00bbVolver a los proyectos\u00bb button_alignment=\u00bbleft\u00bb admin_label=\u00bbBot\u00f3n Dorado\u00bb module_id=\u00bbbotons\u00bb module_class=\u00bbbotons\u00bb _builder_version=\u00bb4.5.7″ _dynamic_attributes=\u00bbbutton_url\u00bb custom_button=\u00bbon\u00bb button_text_color=\u00bb#918050″ button_border_color=\u00bb#918050″ button_icon_color=\u00bb#918050″ button_on_hover=\u00bboff\u00bb hover_enabled=\u00bb0″ custom_css_main_element=\u00bbmargin-top: 10px;\u00bb custom_css_after=\u00bb margin-left: 0px !important;\u00bb button_text_color_hover=\u00bb#918050″ button_border_color_hover=\u00bb#918050″ button_border_radius_hover=\u00bb0″ button_letter_spacing_hover=\u00bb0″ saved_tabs=\u00bball\u00bb button_text_size__hover_enabled=\u00bboff\u00bb button_one_text_size__hover_enabled=\u00bboff\u00bb button_two_text_size__hover_enabled=\u00bboff\u00bb button_text_color__hover_enabled=\u00bbon\u00bb button_text_color__hover=\u00bb#918050″ button_one_text_color__hover_enabled=\u00bboff\u00bb button_two_text_color__hover_enabled=\u00bboff\u00bb button_border_width__hover_enabled=\u00bboff\u00bb button_one_border_width__hover_enabled=\u00bboff\u00bb button_two_border_width__hover_enabled=\u00bboff\u00bb button_border_color__hover_enabled=\u00bbon\u00bb button_border_color__hover=\u00bb#918050″ button_one_border_color__hover_enabled=\u00bboff\u00bb button_two_border_color__hover_enabled=\u00bboff\u00bb button_border_radius__hover_enabled=\u00bbon\u00bb button_border_radius__hover=\u00bb0″ button_one_border_radius__hover_enabled=\u00bboff\u00bb button_two_border_radius__hover_enabled=\u00bboff\u00bb button_letter_spacing__hover_enabled=\u00bbon\u00bb button_letter_spacing__hover=\u00bb0″ button_one_letter_spacing__hover_enabled=\u00bboff\u00bb button_two_letter_spacing__hover_enabled=\u00bboff\u00bb button_bg_color__hover_enabled=\u00bboff\u00bb button_one_bg_color__hover_enabled=\u00bboff\u00bb button_two_bg_color__hover_enabled=\u00bboff\u00bb][\/et_pb_button][\/et_pb_column][\/et_pb_row][\/et_pb_section]<\/p>\n","protected":false},"excerpt":{"rendered":"
