How is the change in internal energy of a system related to heat and work?

Solution: Here, we are going to write the basic SI units for wavelength, frequency and speed of light. Step1: The International System of Units abbreviated as SI units is a universal system of units and has been developed on the basis of the metric system. In SI there are seven basic units which are independent physical quantities and are one dimensional. Step2: a) The distance between two adjacent crests or troughs is called wavelength. It is denoted by the greek letter lambda() and is generally expressed in terms of Angstrom units(A...
