The question is about Distance and Displacement. Distance, a scalar quantity, represents the total path length traveled between two positions, whereas displacement, a vector quantity, refers to the change in position from the starting to the final point, including direction.
When comparing distance and displacement in the field of science, specifically physics, there are key differences to keep in mind. Distance is a scalar quantity that refers to the total length of the path traveled between two positions. In contrast, displacement is a vector quantity—and thus includes both magnitude and direction—that represents the change in position of an object from its starting point to its end point.
Let's consider an example where you drive from home to school which is 5 km away, then return back home. In this case, the distance you traveled is 10 km because distance simply adds up all the lengths covered. However, the displacement is 0 km because displacement considers the direct path from the starting position to the final position; since you returned home, your initial and final positions are identical, and so the change in position is null.
Therefore, it's important to note that while distance and displacement can sometimes share the same magnitude, they are distinct in that displacement always includes direction. Distance is just a measure of how far an object has travelled, while displacement tells you how far and in which direction it is from the starting point.

Answer:
Distance is a scalar quantity that refers to "how much ground an object has covered" during its motion. Displacement is a vector quantity that refers to "how far out of place an object is"; it is the object's overall change in position.
Light from the stars is visible light and travels in longitudinal waves. Longitudinal waves require a medium to travel; therefore, light is reflected off particles of matter in space to be seen on the earth.
B.
Light from the stars is visible light and travels as surface to surface waves. Surface waves require a medium to travel; therefore, light travels from the surface of the star to the surface of the earth.
C.
Light from the stars is visible light and travels in electromagnetic waves. Electromagnetic waves require a medium to travel; therefore, light is reflected off particles of matter in space to be seen on the earth.
D.
Light from the stars is visible light and travels in electromagnetic waves. Electromagnetic waves do not require a medium to travel; therefore, light travels through the vacuum of space to be seen on the earth.
