About This Product
Narrowing or widening the slit in steps lets students see the diffraction envelope spread, fringes sharpen and the beam dim or brighten. It suits wave optics practicals where slit width is the variable under study.
Frequently Asked Questions
How far does the Adjustable Slit open?
The width can be adjusted continuously from 0 mm to 4 mm using its screw control.
