Concept:
When a ray of light travels from one medium to another with a different refractive index, the angle of deviation is the angle that results from the difference between the angles of incidence and refraction.
The optical medium's refractive index is a dimensionless number that indicates how well the medium bends light.
Given:
The angle of the prism is .
The refractive index of the prism is .
Find:
The minimum deviation of the ray of light.
Solution:
The angel of prism,
The refractive index,
The ray of light when incident on a prism and if the ray passes symmetrically.
Then,
Now, the refractive index can be given as:
Where is the angle of deviation.
The minimum deviation is .
