Sample+1.4

I chose this as my “poor” sample because the student shows little understanding of light. The student seems to think that speed has something to do with whether light can be seen. I’m not sure where he got this idea. He is right in thinking that only certain frequencies of light are visible, but the gaps in the hydrogen spectrum are in the visible area of the spectrum. He should know that if the frequencies between the bands were there we should be able to see them.
