What do Newton's Rings demonstrate?

• A. The properties of lenses
• B. The behavior of light in vacuum
• C. Interference patterns from reflective surfaces
• D. The effects of light on color perception

Answer: (C)

Newton's Rings demonstrate interference patterns resulting from the interaction of light reflected between two surfaces, specifically a curved lens and a flat glass plate. When monochromatic light is shone on this setup, some of the light reflects off the upper surface of the lens and some off the lower surface of the glass plate. The light waves that reflect from these two surfaces can constructively or destructively interfere with one another, creating a series of bright and dark rings that are observed as interference patterns. These patterns are directly related to the wavelength of the light used and the varying distances between the two surfaces at each point, illustrating the phenomenon of light interference very clearly. This concept is pivotal in understanding wave optics and is used in various applications, including determining the wavelength of light and testing the quality of optical surfaces.
