Right, the camera we used to record the video also picks up infra-red light. If you try this in person you won’t be able to see infra-red with your own eyes. By the way most cell phone cameras can also pick up infra-red.
In the second video I saw the light not through the camera when he pressed the remote. Is that because you guys were videoing the lesson video with a camera or how did I see it?
There’s a much longer video at the start of this unit that covers the different wavelengths in much more depth. I would start with that video first. Look for the first unit in the experiment section to access it.
Why doesn’t this teach my children anything about infra red light, other than the fact that infra red doesn’t work through opaque objects? There is no information about infra red in the videos. Just two experiments.
