Optics.
Metallurgy
That branch of science is called thermodynamics.
biochemistry is the branch of science concerned with the chemical cocerned
the branch of science concerned with fossil animals and plants.
Nosology
The branch of science concerned with the structure of matter is called chemistry. Chemistry explores the composition, properties, and behavior of substances at the atomic and molecular levels. It seeks to understand how atoms and molecules interact to form different types of matter.
Optics (a branch of physical science that deals with light and vision) and meteorology (the science of atmosphere and weather) are the branches of science which deals with rainbows.When a beam of white light is shone through water, it bends as water impedes its speed. This phenomenon is called refraction.Each constituent colour of the white light travels at a different speed. Red travels faster and is least refracted, violet is most refracted. The result is that light gets split into its constituent colour spectrum. This is called dispersion.A rainbow is nothing but white light dispersed in the sky. It is formed when the sun shines on droplets of moisture in the atmosphere. That is why it is seen during the rains.Thus, the branch of optics and meteorology are the branch of sciences that are concerned with rainbows.
thermodynamics
Ichthyology is the scientific study of fish.
Earthquake science is more properly entitled seismology.
