Answer:
Blue light
Explanation:
Gases and particles in Earth's atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves.
Answer:
I. They come from sources across space
II. They travel in a straight line from their source.
III. They can be reflected by some types of material.
Explanation:
Light wave can be defined as an electromagnetic wave that do not require a medium of propagation for it to travel through a vacuum of space where no particles exist.
The following statements about light waves are true;
I. They come from sources across space.
II. They travel in a straight line from their source.
III. They can be reflected by some types of material. reflection occurs when a ray of light or wavefronts bounces off a smooth surface. Thus, when light hit a surface, it bounces back to the medium from which it was originally propagated with.
However, light waves cannot travel through all type of material except materials that are transparent or translucent but not opaque.
