Sorry I can't be with you guys today. If your class was canceled, the worksheet (Electromagnetic spectrum) you need to complete can be found under homework docs. You may use your textbook, the powerpoint at the bottom of the page or the internet to do so. You will need to do research to find most of the answers.
Also, there may be a box set up in the HMO for you to hand in your project. Please double check if there's a place to drop it off, rather than just holding on to it. If there is a drop off spot and you wait until tomorrow to hand it in, it may be considered late.
