Você sabe como os controles remotos funcionam? [...] De modo geral, os controles remotos em uso atualmente são baseados em dois tipos de tecnologias, a de infravermelho e a de radiofrequência — e os televisores e aparelhos semelhantes que temos em nossas casas tendem a utilizar a do primeiro tipo. Basicamente, os controles remotos via infravermelho funcionam como transmissores — que emitem pulsos de luz invisíveis aos nossos olhos que transmitem sinais aos aparelhos controlados por eles [...]. Com base nesse texto, os controles emitem sinais aos aparelhos receptores por meio de a) descarga elétrica. b) ondas mecânicas. c) partículas carregadas. d) radiação eletromagnética.
