Ideal for advanced physics lessons, this electron diffraction tube enables students to directly observe the wave nature of electrons, supporting practical exploration of atomic structure. Designed for Key Stage 5 and college use, it provides clear visualisation of electron interference patterns, making complex quantum concepts accessible in the classroom.
