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 9
A glass prism has a refractive index of 1.6. If the angle of the prism is 45°, what is the angle of minimum deviation? (Use the formula: n = sin[(A + D)/2] / sin(A/2))
A prism has a refracting angle of 60°. If the angle of minimum deviation is 40°, calculate the refractive index of the prism. (Use the formula: n = sin[(A + D)/2] / sin(A/2))
A prism is made of a material with a higher refractive index. Will the angle of deviation for a given angle of incidence increase or decrease?
A ray of light enters a prism at an angle of 30° to the normal. If the refractive index of the prism is 1.5, calculate the angle of refraction inside the prism. (Use Snell's Law: n₁sinθ₁ = n₂sinθ₂, n₁=1 for air)
Describe the difference between a right-angle prism and a triangular prism.
Describe what happens to a beam of monochromatic light when it passes through a prism.
Describe what is meant by the term 'angle of minimum deviation' for a prism.
Explain why a prism causes white light to form a spectrum of colors.
Explain why a prism produces a spectrum but a rectangular glass slab does not.
Explain why red light deviates less than violet light when passing through a prism.
Explain why the spectrum produced by a prism is continuous and not discrete.
State one practical application of prisms in everyday life.
State the relationship between the refractive index of a prism and the angle of minimum deviation.
The refractive index of a prism for red light is 1.5 and for violet light is 1.6. Which color will deviate more?
What is a prism in the context of optics?
What is the angle between the two refracting surfaces of a typical triangular prism called?
What is the formula for the angle of deviation (δ) in a prism in terms of the angle of incidence (i), angle of emergence (e), and the angle of the prism (A)?
