(Will give brainliest) Describe the difference between red and blue wavelengths of light and why it is important to understanding the movement of galaxies.

B. that is the answer

1) what is light? light is an electromagnetic wave visible to the human eye.  2) what is a reflection? the rebounding of a light ray when it hits a mirror.3) what is the incident ray? contacts the surface of an object.4) what is the reflected ray? bounces off a reflective surface.5) what is the normal ray? perpendicular to the surface of a mirror.6) what is the angle of incidence? an angle formed by the incident ray and the normal.7) what is the angle of reflection? an angle formed by the reflected ray and the normal.8) what is refraction? (bending.)9) what is a converging lens? bring together light rays that pass through.10) what is a diverging lens? spreads out light passing through.11) focal point? the real point where the refracted rays meet when the incident rays run parallel.

Ruth ford over turned thomsons model in 1911 with his well known gold foil experiment in which he demonstrated that the atom has a tiny heavy nucleus rutherford designed an experiment to use the alpha particles emitted by a radio active element as probes to the unseen world of atomic structure. hey hope this
