<P style="MARGIN: 0in 0in 0pt" class=MsoNormal><FONT size=3 face="Times New Roman">Jodi McCullough shared some LED’s from a light set bought at Big Lots ($20 for 100 lights).<SPAN style="mso-spacerun: yes"> </SPAN>They fire white one direction and colors (yellow, red, green, blue) in the other direction.<SPAN style="mso-spacerun: yes"> </SPAN>She cut them into 4 bulb strings, placed them in an L shape on black foam core board, and lit them with 2-nine volt batteries in series.<SPAN style="mso-spacerun: yes"> </SPAN>She used these in color mode as her object for a lens lab.<SPAN style="mso-spacerun: yes"> </SPAN>Allows students to easily see reversals, reasonably measure image height and as Jim Andrews noted were bright enough to use in full room light.</FONT></P>

<P style="MARGIN: 0in 0in 0pt" class=MsoNormal><FONT size=3 face="Times New Roman">Jim Andrews discussed the <st1:place><st1:PlaceName>College-High</st1:PlaceName> <st1:PlaceType>School</st1:PlaceType></st1:place> program as it applies to Physics at YSU.<SPAN style="mso-spacerun: yes"> </SPAN>He and Gregg Sturrus indicated that many local high schools have indicated interest in the program with a large number of high school students potentially receiving credit for physics 1501 through YSU. Discussion ensued about how the program will be run, if you are interested and haven’t been in contact with the university, you should call Gregg at the physics department.<SPAN style="mso-spacerun: yes"> </SPAN>Jim also shared some high powered (50 mW) green laser pointers the department purchased over the internet for about $15.<SPAN style="mso-spacerun: yes"> </SPAN>He first discussed how these use high powered infrared 808 nm (infrared) to pump a material to 1064 nm and this then feeds a frequency doubler that produces the 532 nm green light.<SPAN style="mso-spacerun: yes"> </SPAN>These laser pointers are still class IIIb, but are much brighter than the original 5 mW ones.<SPAN style="mso-spacerun: yes"> </SPAN>The original design also had a filter to block any of the higher powered UV that might escape.<SPAN style="mso-spacerun: yes"> </SPAN>Upon further investigation, they found that the new pointers lacked this blocking filter and when investigating the output in infrared it appears that there is more UV power output than green, causing great concern about the safety of these laser pointers.</FONT></P>
