Doppler Effect Equation

Doppler Effect Equation

Doppler Effect Equation: The Austrian Physicist Christian Doppler formulated the Doppler effect in 1842. According to him, Doppler effect is nothing but the change in wave frequency when an observer is moving with respect to the source. Let us consider an example, if a stationary observer on a platform listen to the sound of the …

[Solved] – Is Condensation Exothermic or Endothermic

Condensation Exothermic or Endothermic

Condensation takes place when the gaseous particles change themselves into a liquid state. It is an exothermic process. The gaseous particles have more heat than liquid. On losing heat, the temperature becomes lower than the boiling point. Hence, they change their state into liquid. To a particular situation, gas particles have a sufficient temperature. When …
