The hotter an object is, the more infrared radiation it emits. Infrared radiation is a type of electromagnetic radiation, which involves waves rather than particles. This means that, unlike conduction and convection, radiation can even pass through the vacuum of space.
Answer:
the width of the central bright fringe reduces
Explanation:
In a single-slit diffraction experiment, if the width of the slit through which light passes is increased, then the width of the central bright fringe reduces.
Example, if the width of the slit is doubled, then the width of the central bright fringe will be halved.
Thus, for single-slit diffraction experiment, increase in the width of the slit through which light passes will result in a corresponding decrease in the width of the central bright fringe.
Answer:
Explanation:
V(x,y)=(x+6)i+(y-3)j ............eq1
As intial point are given (1,1)
which means x=1,y=1
put these values in eq1
V(1,1)=(1+6)i+(1-3)j
V(1,1)=7i-2j
And its magnitude given as
|V(1,1)|=
|V(1,1)| =7.28
