Light interference plates IP-5N


【Product Description】

The light interference plates consist of two glass plates and other experimental material for students learning about the interference of light as one of the light properties.

【Overall Advantages to Users】

  • The interference plates are used to observe the interference pattern of light that appears on the glass plates when the plates have a thin air layer between them. The purpose is to find out the reason why this happens.
  • It is possible to measure the unknown thickness of a thin film that is placed between two plates according to the measurement of interval distance of two dark fringes under a monochromatic light such as Sodium light (if its wavelength is known).
