Define the following branches of physics:

Biophysics: It is the branch of physics that applies the principles of physics to biological systems.

Astrophysics: It deals with the study of celestial objects and the physical processes occurring in space.

Optics: It is the branch of physics that studies the behavior of light and its interactions with matter.

Relativistic Mechanics: It studies the motion of objects moving at speeds comparable to the speed of light, incorporating Einstein’s theory of relativity.

Nuclear Physics: It is the branch that studies atomic nuclei, their components, and their interactions.

Acoustics: It deals with the study of sound and its properties, such as reflection, refraction, and transmission.

Computational Physics: It involves using numerical methods and algorithms to solve complex physical problems.
