COMPLETE EXPERIMENTS ON OPTICS

Objective: Determine the focal length of a lens using the Bessel method On an optical bench it is possible to set up a light source, a lens, a screen and an object to be imaged in such a way that a well focussed image appears on the screen ... more

Objective: Generating interference between two beams using a Fresnel biprism. Refraction of a divergent light beam by means of a biprism separates the beam into two parts which, since they are coherent, will interfere with one another. The ... more

Objective: Demonstration of Pockels effect in a conoscopic beam path The Pockels effect is an electro-optical effect in which an electric field within a suitable material splits a light beam into two beams polarised perpendicular to one ... more

Objective: Verify that intensity of radiation is proportional to the fourth power of the temperature, T4 The way that intensity of radiation from a black body depends on temperature is described by the Stefan-Boltzmann law. Similar ... more

Objective: Determine the velocity of light from the transit time of short light pulses The fact that light is propagated at a finite speed can be demonstrated by a simple transit time measurement. This is achieved by using very short light ... more
