THE PHENOMENON OF DIFFRACTION

Matt Baker, Head of Secondary Science

Y

ear 13 IB Physics students used their knowledge of the phenomenon of diffraction to calculate the width of a human hair. They focussed lasers onto human hair plucked from their own heads and projected the image onto the whiteboard. By taking careful measurements from the resulting diffraction pattern and the distance of the hair from the board they could then calculate the diameter of the hair. The students then confirmed their results by an alternative method; they measured the diameter of the hair directly with a micrometer screw gauge. The agreement between the two results was impressive! The students then consolidated their learning by completing some practice questions. The twist was that they used the windows in the classroom to display their answers; this allowed their learning to be highly visible and facilitated the feedback process from their peers and teacher.
