Newton's Ring Experiment instrucment/University Physics experiments

Product Description:

The phenomenon of Newton's rings, named after Isaac Newton, is an interference pattern caused by the reflection of light between two surfaces - a spherical surface and an adjacent flat surface. When viewed with monochromatic light, it appears as a series of concentric, alternating light and dark rings centered at the point of contact between the two surfaces. Using this apparatus, students can observe the phenomenon of equal-thickness interference. By measuring interference fringe separation, the radius of curvature of the spherical surface can be calculated.

Experiments:

● Observe the Newton's ring interference phenomenon, and get familiar with the experimental equipment

● List the measurement data and learn how to reduce the systematic errors

● Understand the principles of the Newton's ring experiment and master the concept of its interference

● The basic principle of determining the radius of curvature of a convex lens by using a Newton's ring
