...: https://shorturl.at/dejkP ). Topic area: Light/geometric optics Geometric optics is a topic area related to light phenomena and to quantitative relationships without delving into the nature of these phenomena (i.e., principle of minimum time, refraction, reflection). According to the literature, using...

..., 2008 ). For example, in one of our lab studies, students were tasked with measuring the index of refraction of a piece of plexiglass using three different methods and then to determine the best estimate of the index of refraction using a weighted average. Many students simply combined the three...

..., or the simple intensity of light, are estimated and measured with a luxmeter ( Gostinčar Blagotinšek, 2021 ). The law of reflection is assessed with activities with one or two flat or curved, fully reflective, or semi-transparent mirrors. The refraction of light is sometimes studied with simple imaging of near...
