Question

What do you understand by Rectilinear propagation of light? (1) ii) What is Lunar eclipse? (2)
​

Answer 1

Answer:

1 .Rectilinear propagation describes the tendency of Electromagnetic waves (light) to travel in a straight line. Light only deviates from a straight line when the medium it is travelling through changes density. This is called refraction.

2 .A lunar eclipse heightens the energy of the full moon and is a time to embrace endings and let go of things that are no longer serving you—ready or not. This may happen abruptly at these supercharged full moons—a situation or person can literally be "eclipsed" out of your life.
