Q. Eclipses occur due to which optical phenomena?
A. Reflection
Answer: Rectilinear propagation
An eclipse is an astronomical event that occurs when an astronomical object is temporarily obscured, either by passing into the shadow of another body or by having another body pass between it and the viewer. This alignment of three celestial objects is known as a syzygy. Apart from syzygy, the term eclipse is also used when a spacecraft reaches a position where it can observe two celestial bodies so aligned. An eclipse is the result of either an occultation (completely hidden) or a transit (partially hidden).
In a homogenous transparent medium, light travels in a straight line and this is known as the rectilinear propagation of light.
Light does not travel like an average projectile. Light is said to have a dual nature. It has properties of a particle and of a wave but does not travel like an average particle as we have just discussed, nor does it travel like a water wave or a sound wave.
