Who among the following scientists was the first to use a glass prism to discover the spectrum of sunlight? 

The correct answer is Sir Isaac Newton.

Key Points

• Sir Isaac Newton was the first scientist to use a glass prism to discover the spectrum of sunlight.
• He conducted the experiment in 1666, demonstrating that white light is composed of different colors.
• Newton's work laid the foundation for the field of optics.
• He published his findings in the book "Opticks" in 1704.

Additional Information

• Prism:
  • A prism is a transparent optical element with flat, polished surfaces that refract light.
  • Prisms can be used to break light up into its constituent spectral colors (the colors of the rainbow).
• Optics:
  • Optics is the branch of physics that studies the behavior and properties of light.
  • It includes the study of reflection, refraction, dispersion, and the interaction of light with matter.
• White Light:
  • White light is a combination of all colors in the visible spectrum.
  • When passed through a prism, white light is dispersed into its component colors.
• Newton's Contributions:
  • Isaac Newton made significant contributions to mathematics, physics, and astronomy.
  • He is also known for his laws of motion and universal gravitation.
