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 10
A glass prism has a refractive index of 1.5. If the angle of the prism is 30^\circ and the angle of minimum deviation is 20^\circ, verify if the given values are consistent using the prism formula.
A prism has an angle of 30^\circ and a refractive index of 1.5. What is the minimum deviation produced by the prism?
A prism has an angle of 45^\circ and the minimum deviation is 30^\circ. What is the refractive index of the prism?
A ray of light enters a prism with an angle of incidence of 45^\circ, the angle of the prism is 60^\circ, and the refractive index is 1.6. Calculate the angle of refraction at the first face using Snell's law.
Describe how a prism is used in a spectrometer.
Describe the difference between a dispersive prism and a reflecting prism.
Describe the path of a monochromatic light ray through a triangular prism.
Explain why a prism disperses white light but a rectangular glass slab does not.
Explain why the deviation produced by a prism increases with the refractive index of the material.
Explain why the refractive index of a prism is different for different colors of light.
If the angle of the prism is 60^\circ and the angle of minimum deviation is 40^\circ, calculate the refractive index of the prism material.
Name the two main types of prisms based on their function in optics.
State the formula for the angle of minimum deviation (D) for a prism in terms of the angle of the prism (A) and the refractive index (n).
What is a prism in the context of optics?
What is the main reason for the dispersion of light in a prism?
What is the minimum deviation position in a prism?
What is the phenomenon called when a prism splits white light into a spectrum of colors?
A ray of light passes through a prism with an angle of 50°. The angle of incidence is 40°, and the angle of emergence is 60°. Calculate the angle of deviation produced by the prism.
A student observes that the spectrum produced by a prism is wider for blue light than for red light. Explain the reason for this observation.
A triangular glass prism is placed in air. If the speed of light in glass is 2 \times 10^8 m/s and in air is 3 \times 10^8 m/s, calculate the refractive index of glass with respect to air.
