Difference between reflection and absorbrion of sound give a answer of 15 words |
|
Answer» ion means that something is thrown back. If, for example, a ball is thrown against a wall and it comes back, one could SAY that it has been reflected. The same happens with sunlight meeting the surface of the EARTH: It is being reflected and can thus be collected by a remote sensing sensor.If the light makes contact with a smooth surface such as a MIRROR the equation is: angle of INCIDENCE = angle of reflection. There are generally three types of light reflections. However, please note that the reflection depends UPON the surface roughness of an object. |

Answer in one sentence ...1)what do you meran by a state variable of a system? |
|
Answer» tion:A state variable is one of the set of variables that are used to describe the mathematical "state" of a dynamical system. Intuitively, the state of a system describes ENOUGH about the system to DETERMINE its future behaviour in the absence of any external forces affecting the system. Models that CONSIST of coupled first-order DIFFERENTIAL equations are said to be in state-variable form. |
