Resumo: <\/strong>Apresentamos neste trabalho as etapas de execu\u00e7\u00e3o de uma atividade pr\u00e1tica para comprovar a velocidade da luz empregando um forno de micro-ondas. Adaptamos o experimento do roteiro proposto por Stauffer em 1997 na revista The Physics Teacher. Conclu\u00edmos que a atividade possibilita estimar a velocidade da luz com um erro inferior a 0,3%\u00a0e contempla o que prop\u00f5e a Base Nacional Comum Curricular para o ensino de Ci\u00eancias da Natureza e suas Tecnologias.<\/em>

Abstract: <\/strong>We present in this work the steps of performing a practical activity to prove the speed of light using a microwave oven. We adapted the experiment from the script proposed by Stauffer in 1997 in The Physics Teacher magazine. We conclude that the activity makes it possible to estimate the speed of light with an error of less than 0.3%\u00a0and contemplates what the National Common Curricular Base proposes for the teaching of Natural Sciences and its Technologies.
