There are three main processes Isothermal, adiabatic and cyclic process. In isothermal, the system is thermally conductive and the temperature remains constant. In adiabatic process, the system is thermally isolated and there is no change in heat temperature. The system returns to its initial stage in the cyclic process.

A wave is a disturbance that transfers energy from one point to another without any net transport of matter.
It involves the oscillation of particles in a medium (or space, for electromagnetic waves) which leads to the propagation of energy.

A frame of reference is a system that helps an observer measure the position, speed, and time of an object. It is important because motion is always relative to something else. Without a frame of reference, we cannot describe how an object is moving or if it is moving at all. It provides a fixed viewpoint to observe and understand motion accurately.

Let us consider a vector . The equation can be written as
Px = Py = 1 = = = …….(i)
So the magnitude of vector + =
Let be the angle made by vector , with the x axis as given in the above figure
= = , = 45 with the x axis

Let = -
– = ( –
= = 1
= =
Hence = . Therefore the magnitude of ( + =
Let be the angle made
