Question

14) With the help of a ray diagram explain the phenomenon of
refraction of a ray through glass prism Mark on the diagram - angle
of prism, angle of incidence, angles of refraction, emergent ray
and angle of deviation

Dear
student,

When light passes through one face of a prism it gets deviated,
this is called 
refraction

This deviation is different for different wavelengths of light
Since different colours of light have a different wavelength, the
deviation for a different colour is different As a result, when the
light emerges from the other face of the prism we observe the seven
constituent of light This phenomenon of the splitting of light into
its constituent Colors is called dispersion
