SHADOWS AND ECLIPSE RESULT FROM THE
- A. Reflection of light
- B. Rectilinear propagation of light ✓
- C. Diffraction of light
- D. Refraction of light
The answer to the question is: B. Rectilinear propagation of light
Shadows and eclipses result from the rectilinear propagation of light. When an opaque object is placed in the path of light, it obstructs the light, creating a shadow. An eclipse occurs when one celestial body moves into the shadow of another celestial body. These phenomena are explained by the rectilinear propagation of light, which states that light travels in straight lines unless it is reflected, refracted, or diffracted.
The rectilinear propagation of light is a fundamental principle in optics. It explains how light travels in a straight line until it interacts with an object or medium. When an opaque object blocks the path of light, it creates a shadow on the opposite side of the object. The size and shape of the shadow depend on the relative positions of the light source, the object, and the surface on which the shadow is cast.
Similarly, during an eclipse, such as a solar or lunar eclipse, one celestial body moves into the shadow cast by another celestial body. This occurs due to the straight-line path followed by light from the Sun or Moon, which creates the shadow that causes the eclipse.
In summary, shadows and eclipses are a result of the rectilinear propagation of light, where light travels in straight lines until it encounters an obstacle or is blocked by another object.
