Thy, Savrin; Iwayama, Tsutomu – Physics Education, 2021
This paper presents a thorough method for studying the interference of water waves. The study aimed: (a) to demonstrate the interaction of two coherent waves, which creates interference patterns, and (b) to analyse the interference patterns. Three main tools were employed: a simplified ripple tank to experiment, a smartphone camera to record the…

Coleman, Aaron B.; Lam, Diane P.; Soowal, Lara N. – Biochemistry and Molecular Biology Education, 2015
Gaining an understanding of how science works is central to an undergraduate education in biology and biochemistry. The reasoning required to design or interpret experiments that ask specific questions does not come naturally, and is an essential part of the science process skills that must be learned for an understanding of how scientists conduct…

Page, A.; Moreno, R.; Candelas, P.; Belmar, F. – European Journal of Physics, 2008
In this paper, we show the potential of webcams as precision measuring instruments in a physics laboratory. Various sources of error appearing in 2D coordinate measurements using low-cost commercial webcams are discussed, quantifying their impact on accuracy and precision, and simple procedures to control these sources of error are presented.…
