Newton's rings are formed due to:
Correct answer: B. Interference
- A. Reflection
- B. Interference
- C. Refraction
- D. All
Explanation
B is the right option because Newton's rings are formed due to the interference of light waves that are reflected and refracted between a lens and a flat glass plate. The interference patterns create a series of concentric colored rings.

About Waves
Progressive waves transfer energy through oscillations, with wavelength, frequency, amplitude and wave speed related by v = fλ; sound speed depends on the medium. Superposition produces interference and stationary waves in strings and organ pipes, while simple harmonic motion describes the oscillation itself and must be distinguished from wave propagation.
