When light hits an object, the object absorbs some of the light and reflects the rest of it. The wavelengths that are reflected determine how our eye perceives the color. Why does the human eye perceive a red colored dress as the color red? a)The moeclues of the dress do not absorb red light wavelengths. b)A red dress will primarily absorb red light wavelengths. c)The molecules of the dress absorb green and blue light wavelengths. d)A red dress will not absorb light wavelengths from non-red colors.

Quantum Chemistry

Quantum chemistry deals with the properties of chemical systems and their reactions. The branch of chemistry which is more concerned with quantum chemistry is physical chemistry. It is a more sophisticated field of theoretical physics which is concerned towards the application of physical concepts towards various chemical aspects such as, formation of atoms, chemical structure descriptions, chemical bond strength, hybridization, conjugation etc. Quantum chemistry mainly studies the various states i.e., ground state, excited state, transition states of the individual atoms or molecules taking place during any chemical reaction. The laws of motion explained by various scientists, which are termed as “classical mechanics” were not acceptable in terms of electrons, protons, atoms, light etc. Thus, a new theory named “quantum mechanics” emerged to understand the basic framework of various atomic and subatomic particles.
