This kit and their associated resources are designed to help teach about double-slit and diffraction patterns.

Before teaching this, students should:

• be familiar with constructive and destructive interference;
• be aware that we get diffraction when a wave travels through a gap;
• ...

The aim of this experiment is for students to be able to determine for themselves the threshold voltage needed to activate a range of LEDs of different colours. From these values, combined with a knowledge of the wavelengths of each LED, students can plot a graph to determine a value for Planck’s constant. The...
