Optically true glass with scratch-resistant, copper back silvering (appears red). Concave mirrors produce real images and convex mirrors produce virtual images.Used for optical experiments such as the law of reflection, and convergence. Great for STEM activities in the classroom, home school and science fairs.

Features:

• 50 mm Diameter
• 100 mm Focal Length
• Demonstrate the Law of Reflection
• Determine how an image is reflected in a concave mirror
