J.T distortion is a type of optical distortion that occurs in lenses.

• It is caused by the lens not being perfectly aligned with the optical axis.

• It can result in distorted or blurred images.

• J.T distortion can be corrected through the use of specialized lenses or software.

• It is commonly seen in wide-angle lenses and can be more pronounced at the edges of the image.

• J.T distortion is named after James Thomson, who first de

CO2 is IR active. IR region ranges from 4000-400 cm-1. Esters have a peak in the 1750-1735 cm-1 region.

• CO2 has a linear structure and has a dipole moment, making it IR active

• IR region is divided into three regions: near-IR, mid-IR, and far-IR

• CO2 absorbs IR radiation in the mid-IR region, specifically around 2349 cm-1

• Esters have a peak in the carbonyl stretching region, which is around 1750-1735 cm-1

The total work done in Carnot cycle is equal to the area enclosed by the cycle on a PV diagram.

• The Carnot cycle is a theoretical thermodynamic cycle that consists of four reversible processes: isothermal expansion, adiabatic expansion, isothermal compression, and adiabatic compression.

• The total work done in the cycle is equal to the difference between the work done during the isothermal expansion and the work done duri...read more
