## Coherent and incoherent addition of waves

If the waves are coherent, then the resultant intensity is given by

I = I1 + I2 + 2 √(I1 I2 Cos Θ), where Θ is the phase difference between two waves.

## Is potential difference is directly proptional to resistance?

Is potential difference is directly proptional to resistance? (atanu asks) Answer: For a constant current, the potential difference is directly proportional to the resistance included in the circuit. For a given conductor at constant temperature, resistance is a constant and the potential difference across it is directly proportional to the current passed through it.

## How graphs are made for different processes like isothermal, isobaric, isochoric & adiabatic?

How graphs are made for different processes like isothermal, isobaric, isochoric & adiabatic? Answer: Hope you are talking about the PV diagrams. The difference between isothermal and adiabatic curve is that the adiabatic curve is more steeper than an the isothermal curve. In isobaric, P remains constant and hence will give a horizontal line (if [...]
