Prisms starts at 9 and continues till grade 12.
QuestionsToday has an evolving set of questions to continuously challenge students so that their knowledge grows in Prisms.
How you perform is determined by your score and the time you take.
When you play a quiz, your answers are evaluated in concept instead of actual words and definitions used.
See sample questions for grade 12
A glass prism has a refractive index of 1.5. If the angle of the prism is 60°, what is the minimum angle of deviation? (Use n = sin[(A + Dm)/2] / sin(A/2))
A prism has an angle of 30° and produces a minimum deviation of 20°. If the refractive index of the material is 1.52, verify if the given values are consistent using the prism formula.
A prism is made of a material with a refractive index of 1.7. If the angle of the prism is 40°, what is the value of sin(A/2)?
A ray of light is incident on a prism with an angle of prism 45° and refractive index 1.6. If the angle of minimum deviation is 30°, calculate the value of sin[(A + Dm)/2].

Fill in the blank: The phenomenon of splitting of white light into its constituent colors by a prism is called __________.
Fill in the blank: The refractive index of a prism is always __________ than 1.
True or False: Dispersion by a prism is a result of the dependence of refractive index on the wavelength of light.
True or False: The angle of deviation is independent of the wavelength of light passing through a prism.
True or False: The deviation produced by a prism increases with increasing refractive index of the material.
True or False: The emergent ray from a prism is always parallel to the incident ray.
