Optics System 2

Code: 4864.29

An intermediate system for geometrical and physical optics

The Optics System 2 is designed to study composition of light, light polarization, refraction index as well as many additional aspects of light reflection and refraction.

The system contains a Hartl apparatus, which allows the student to perform many experiments related to the reflection of light on mirrors and to the refraction through transparent bodies.
Also included is our specially designed Altay Optics Box, designed to investigate polarisation in various solutions. Additionally you can study photoresistance, photometry and verification of Malus’ Law.

EXAMPLE OF USE: Optical activity

Observe the rotation of light using a sugar solution.

Some substances such as sugar will react when a beam of light is incident on it. They rotate the polarisation plane of the light around its direction of propagation.
This optical activity is a phenomenon connected with the “asymmetry by reflection” of the molecules of many substances. The degree of rotation is determined by the rotational power of the optically active solution present and by the amount of molecules of the solution that interact with the beam of light. The directional change of the light is also affected by degree of concentration of the solution and distance the light must travel through it. Other features such as temperature and wavelength of light are also important.

The above formula defines the specific rotatory power of a substance at a given temperature and wavelength.
