Define following terms: i. Longitudinal chromatic aberration  ii. Circle of least confusion  iii. Transverse chromatic aberration

A wave in which particles of medium vibrate in a direction parallel to the direction of propagation of the wave is called longitudinal wave.  Example : Sound waves.

a. Transverse wave : A wave in which particles of the medium vibrate in a direction perpendicular to the direction of propagation of wave is called transverse wave.  b. Longitudinal wave...

1. Oxidant :  Oxidant or oxidising agent is an electron acceptor.  2. Reductant :  Reductant or reducing agent is an electron donor.

i. Oxidation is an increase in the oxidation number of an element in a given substance. e.g. Fe(s)  → \(Fe_{(aq)}^{2+}\) ii. Reduction is a decrease in the oxidation number of an element in a...

i. Period (T): The time taken by the particle of a medium to complete one vibration is called period of the wave. SI unit: second (s) ii. Frequency (n): The number of vibrations performed...

1. Light waves (from Sun to Earth) are electromagnetic waves which are transverse in nature. 2. Ultrasonic waves in air are basically sound waves of frequency greater than the audible frequencies....
