What are the factors on which angular deviation suffered by a light depends, when it passes through a prism?
What are the factors on which angular deviation suffered by a light depends, when it passes through a prism?
The correct option is E Depends on the refractive Index of the material of the prism, Angle of Incidence, Angle of Prism and colour or wavelength of light
The angle between the incident ray extended forward & the emergent ray extended backward is called angle of deviation. It depends on:
i) μ of the prism [greater the μ, greater is the angle of deviation]
ii) Angle of prism “A” [greater the A, greater is the angle of deviation]
iii) Angle of Incidence [As Angle of Incidence increases initially the angle of deviation first decreases and reaches a minimum value, then as the Angle of Incidence is further increased angle of deviation increases]
iv) Colour or λ of light [Smaller the λ, greater is the angle of deviation. Thus angle of deviation is most for violet and least for red colour]
