This modulated semiconductor laser contains two independently controlled laser diodes—a 650 nm red and a 532 nm green—allowing students to directly compare how wavelength affects diffraction

Students immerse a hollow drum covered with a rubber membrane into water and observe how increasing depth produces a clear, corresponding change in the connected manometer. This direct cause and effect setup helps students link
