For this lab, I'm supposed to use materials that heat up but doesn't allow heat to transfer. I've used raw spaghetti noodles already but I still a few more for more trials. So what materials are good for this lab? after heating up the material, I measure the distance between the "hot spots" so I can deduce the wavelength of the standing wave ( I have no clue what that means) and from that determine the speed of light. Is this enough information for someone to help me?
