This apparatus allows students to easily understand the two important wave properties of light, i.e. reflection and refraction.
The apparatus comprises of a ray box and a rotating platform, both of which are mounted on a sturdy base.
Also included, is an acrylic semi-circle that can be filled with different mediums for measuring the index of refraction.
The rotating platform provides a high degree of accuracy when making measurements.
It also ensures an easy way to change angles without disturbing the light source or the object on which the light is being projected.
The ray box comes with single, double, triple and wide slit attachments, two metal shields for blocking light, and an acrylic lens for focusing the beam of light.
This apparatus helps students to use Snell's Law to determine the critical angle of a fluid, to find the index of refraction and to discover the laws of reflection.
