What are the conditions for minimum deviation in a prism?
The condition for minimum deviation through a prism is that angle of incidence (i) is equal to angle of emergence ( e). In that case, the refracted ray EF becomes parallel to the base bC of the prism. Here, μis refraction index of the material of the prism.
What does deviation in a prism depend on?
(i) For a given angle of incidence, the prism with a higher refractive index produces a greater deviation than a prism with a lower refractive index. (ii) The refractive index of a medium is different for light of different colours. It increases with decrease in wavelength.
What does angle of prism depend on?
Since the angle of deviation is calculated using the angle of incidence ray, the angle of deviation depends on the angle of incidence. The Refractive index of the prism is the ratio of the speed of light in a vacuum divided by the velocity of light in the medium.
Does the angle of minimum deviation produced by a prism depend on wavelength?
(i) The angle of minimum deviation produced by a prism decreases with increase in the wavelength of incident light.
How does angle of deviation vary with angle of incidence?
The angle through which the emergent ray deviates from the direction of incident ray is called angle of deviation ‘d’. As the angle of incidence is increased, angle of deviation ‘d’ decreases and reaches minimum value. If the angle of incidence is further increased, the angle of deviation is increased.
How does angle of deviation depends on angle of prism?
so we can say that angle of incidence and angle of the prism will directly affect the angle of deviation and we also know that refractive index is different for different materials so if you change the nature of the material of prism, it will affect how light travels in that medium which will, in turn, affect the angle …
How does the deviation produced by a prism depends on angle of prism?
(ii) The material of prism (i.e, on refractive index) – For a given angle of incidence, the prism with a higher refractive index produces a greater deviation than the prism which has a lower refractive index. (iii) Angle of prism- Angle of deviation increases with the increase in the angle of prism.
How does the angle of minimum deviation produced by a prism change with the increase in wavelength?
As we increase the wavelength, angle of deviation decreases. The angle of deviation increases with the increase in the angle of prism.
What is the relation between angle of deviation and angle of prism?
angle of deviation is directly proportional to angle of prism. if angle of prism increases then angle of deviation increases.
What is the difference between angle of prism and angle of minimum deviation?
Angle of prism: The angle between the two sides of the reflecting faces of prism is called angle of prism. Angle of deviation (δ): Angle between the incident ray and the emergent ray is called the angle of deviation.
