Details: Dimensions: 75 mm x 25 mm The Mirror Strips (75 x 25 mm) are precision-cut plane glass mirrors designed for use in optics experiments, science demonstrations, and laboratory instruction. With a smooth reflective surface and accurately finished edges, these strips are ideal for studying the laws of reflection, image formation, ray tracing, and other fundamental optics principles. Compact and easy to handle, these mirror strips are a staple item in school and college physics laboratories, commonly used alongside optical pins, ray boxes, and drawing boards for reflection and refraction experiments.
