1. Which of the following is NOT true for electromagnetic waves. (a)they consist of changing electric and magnetic fields. (b) they travel at different speeds in vacuum, depending on their frequency. (c) they transport energy (d) they transport momentum. (e)they can be reflected.
How can we create a representation showing that matter is made of particles too small to be seen? Does matter still exist if you cannot see it? I can explain that matter is made up of particles too small to be seen. I can develop a model to describe phenomena. In what ways can matter change?
LAB: Electric Field Lines. Purpose:To investigate the direction and magnitude of electric field lines that are created around positive and negative charges. 1. Open the Charges and Fields simulator on the PhET website. hint : Download the file, save then run the .jar file.
