Question

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. what types of electromagnetic waves allow them to be used for short - distance communication? what properties of electromagnetic waves allow them to be used for long - distance communication? what types of electromagnetic waves allow them to be used for long - distance communication? what properties of electromagnetic waves allow them to be used for short - distance communication?

Explanation:

The students are comparing radio and television broadcasts which are long - distance communication methods. They are looking at how electromagnetic waves' properties (refraction and diffraction) help in these broadcasts. So, a question about the properties of electromagnetic waves for long - distance communication is most appropriate.

Answer:

What properties of electromagnetic waves allow them to be used for long - distance communication?
