Question

Give the theory of reflection of electromagnetic wave from metallic surface . Hence obtain the value of optical constants of a metal.​

Answer 1

Answer:

The criterion to determine if adults are undernourished is Body Mass Index, popularly known as BMI. (ii) In order to calculate it, first the weight of the person in kg is taken. Then, we take height in meters. The weight is divided by the square of the height

Answer 2

[Answer]

THEORY OF REFLECTION  OF ELECTROMAGNETIC WAVE METALIC  FROM SURFACE.

➤  Electromagnetic waves involves in returing or throwback from a surface      of it insidence with no much  loss of energy while collosion of  Protons and           electrons of that wave .

➤  As common  reflecting sector is the boundary between two materials

    of different electro magnetic sectors properties

                              ▾

    Æxample - ( air ,water )  ( air, glass)  ( air ,metal ) .

✎. The refletivity of polished metal surface is quit higher

      more than 90 percent of visible light.

     

     The reflectivities are vary considerable with wavelenth  

     generaly as  off to the shortest wavelenth .

ON METALS

• Totaly surface says that how refllection takes place ,so due to                          
• oxidation on metal surfaces ( usual decreases happens ) in reflectivity.
• Acts like a interface between air and metal                                                        

★ ALUMINIUM HAS HIGH REFLECTIVE AND DETERIORATES  RELATIVELY LITTLE IN ATMOSPHERE.
