Students’ have varying levels of understanding of light matter interactions in chemistry contexts. This study investigated students’ understanding through the use of semi-structured interviews and PhEt simulations of both the single slit and double slit experiments. Coding qualitative analysis and construct maps were used to assign students to specific levels of sophistication. It was found that students’ carry differing levels of understanding of light and light matter interactions where low level learners struggled to connect ideas in their explanations while high level learners had strong connections between their knowledge and explanations.
