The Doppler effect is a shift in the frequency of waves emitted from an object moving relative to the observer. By observing and analysing the Doppler shift in electromagnetic wave…
The atmospheric extinction of light
Stephen W. Hughes, Michael J. Cowley, Sean Powell +1
An experiment is described that enables students to understand the properties of atmospheric extinction due to Rayleigh scattering. The experiment requires the use of red, green an…
Parallax in the park
Stephen Hughes, Sean Powell, Joshua Carroll +1
This article describes a parallax experiment performed by undergraduate physics students at Queensland University of Technology. The experiment is analogous to the parallax method…
Characterization of transiting exoplanets by way of differential photometry
Michael Cowley, Stephen Hughes
This paper describes a simple activity for plotting and characterizing the light curve from an exoplanet transit event by way of differential photometry analysis. Using free digita…
