Question

Experiment to determine the refractive index of a glass prism

Answer 1

Take a plane mirror of a suitable size.place it in a bowl .fill the bowl with water.put this arrangement near a window in a such a way that direct sunlight falls on the mirror(you can also use a powerful torch light).adjust the position of the bowl so that the reflected light from the mirror falls on a wall.what do you observe?the mirror and the water combination acts like a prism.it breaks up the light into its colors,i.e. shows the phenomenon of dispersion of light.
