As we continue to study waves, today we took a deep dive into electromagnetic waves. Electromagnetic waves consist of a spectrum  of waves from Radio waves with the longest wavelength, down to gamma waves with the smallest. In class we used microwaves and chocolate bars to measure the speed of light, which is the speed at which all EMS waves move.

We continued our investigation of waves with a little help from everyone's favorite Science Guy.

Return of the Gold Tape Question!!!
After too long a hiatus, GTQs are back. For this week's question, watch (and more importantly listen to) the video to the right of legendary rock band The Grateful Dead performing their classic song "Ripple." Your task is to identify and explain at least 4 examples of waves that can be found in the lyrics to the song. You can comment or email your responses.

Congratulations on finishing up your CMAS testing. We are continuing our energy unit in a new direction and that is the direction of waves. We will be investigating both transverse and longitudinal waves, as well as electromagnetic and sound waves. All waves have similarities with each other but different types of waves also have unique characteristics that we will discover during our new unit.
