A rainbow is a meteorological phenomenon that is caused by reflection, refraction and dispersion
of light in water droplets resulting in a spectrum of light appearing in the sky. It takes the form
of a multicoloured circular arc. Rainbows caused by sunlight always appear in the section of sky
directly opposite the sun.
Objective: This research reveals the physics behind the creation of rainbows and to find out "Is the artificial
creation of rainbows help full in any way when it comes to our understanding of ways in which light works.
A project to:
Determine the dependence of the sample stream on the voltage at zero magnetic induction.
Find the dependence of the Hall voltage on the magnetic induction at two values of constant current sample.
Process the measurement results graphically and evaluate conductivity and Hall effect sample.
Calculate the mobility and concentration of charge carriers.
