In this activity students use the known speed of earthquake waves to estimate the Young's modulus of the Earth's crust.
In this small group activity, students work out the steady state temperature of an object absorbing and emitting blackbody radiation.
In this activity students estimate the optical depth of the atmosphere at the infrared wavelength where carbon dioxide has peak absorption.
Students work in a small group to write down an equation for a travelling wave.
Each small group of 3-4 students is given a white board or piece of paper with a square grid of points on it.
Each group is given a different two-dimensional vector \(\vec{k}\) and is asked to calculate the value of \(\vec{k} \cdot \vec {r}\) for each point on the grid and to draw the set of points with constant value of \(\vec{k} \cdot \vec{r}\) using rainbow colors to indicate increasing value.
