Use the scenario to answer the following question.
Students are investigating the properties of electromagnetic waves. Part of their investigation requires students to compare and contrast different types of communication such as radio and television broadcasts. Students determined that radio and television broadcasts are able to be heard and viewed because the electromagnetic waves are refracted and diffracted as they encounter obstacles.
Identify the BEST question students would use to guide their investigation.
