Laser Ray Box
Product Code : SCL-EAE-11128
Quick answer: The Laser Ray Box projects visible rays of light so that students can see and trace light paths in optics practicals. It is used with mirrors, lenses, prisms and transparent blocks to verify the laws of reflection, study refraction and show how convex and concave lenses converge or diverge rays. Lab Exports manufactures it in Delhi for schools, colleges and universities.

How the laser ray box experiment is done
A narrow, bright laser ray stays sharp across a whole sheet of paper, so the incident and emergent rays can be marked with a pencil and joined up afterwards. This turns textbook ray diagrams into measurements: at a plane mirror the angle of incidence equals the angle of reflection, and at a boundary between air and glass the ray bends according to Snell's law, n1 sin i = n2 sin r.
- Place the ray box on a stable table with a sheet of paper as the ray-tracing surface.
- Connect the power source as given in the supplied instructions.
- Set the mirror, lens, prism or block on the paper in the path of the ray and switch on.
- Mark points along the incident and emergent rays, then switch off and draw the ray paths.
- Measure the angles with a protractor and compare them with the laws of reflection or refraction.
With a convex lens, parallel rays meet at the principal focus; with a concave lens they spread out as if from a focus behind the lens. Never look into the laser aperture or point the beam at anyone's eyes, and keep reflecting surfaces angled down towards the bench.
