A simple presentation to aid explanation of the role of radiation intensity in the photoelectric effect once the threshold frequency of the metal has been exceeded. Students often misunderstand the inability of increased intensity to trigger the photoelectric effect and therefore believe it has no role. This presentation is a visual aid to help the teacher show that it has a role in controlling the number of photons arriving per unit time. This presentation compares a source of low intensity blue with high intensity blue light (where blue light has a frequency above the threshold frequency). This is a Keynote presentation (macOS, iPadOS and iOS). Useful for all A-Level physics specifications. The photoelectric effect is an important experiment in physics that proves that light behaves like a particle, it was a founding experiment for quantum theory. Einstein won his Nobel prize for his work on explaining the photoelectric effect.

Copy of the spreadsheet I used to analyse the experiment to estimate Planck’s constant in this video. The spreadsheet automatically calculates photon energy from inputted potential difference readings. The data plots are added to a carefully formatted graph. A line of best fit is automatically plotted. The gradient and y-intercept of the line are automatically calculated from the data plots and the estimate for the Planck constant is calculated from the gradient. This spreadsheet is perfect for rapidly analysing experimental data. This is a Numbers spreadsheet. It is possible to convert Numbers spreadsheets to Excel files but I cannot guarantee an easy to use output since the tables may be converted to separate worksheets in the Excel file. Suitable for most A-Level Physics specifications.

Help your students practice recall of graph shapes and features across most physics subject areas (A-level and equivalent). This activity is differentiated. Included is a PDF that has two versions of blank graph grids for students to draw onto. The first version has no help beyond quantities labelled on the axes. The +1 version has some additional guidance included on the axes / grid (such as intercepts or markers). For more guidance there is a page of all graph shapes that students can select from. Also included in this resource is a Keynote¹ slideshow that has an introduction and solutions. The introduction and solutions are included in the PDF document; printing them is optional. The slideshow solutions show the same grids empty to begin with and the lines are animated. This gives the option of an interactive activity with your students in which you can select students to draw their solution, compare to the textbook answer and discuss any differences (interactive whiteboard or similar required). A non-differentiated version of this activity without slideshow is available for free.
