Find amplitude of electric field ina parallel beam of light of intensity 2W/m2Ans:Given that intensity I=power/area=2W/M2by using this formula :intensity I=(Emax^2/2c mue not)from that Emax=magnitude of electric fieldc=velocity of light=3*10^8m/secmue not =4pi*10^-7Emax=38.82 N/m
Calculate the density of silver which crystallizes in the face-centred cubic structure. The distance between the nearest silver atoms in this structure is 287 pm. (Molar mass of
Refractive index: The most important optical measurement for any transparent material is its refractive index (n). The refractive index is the ratio of the speed of light (c)
Cadmium rods are provided in a nuclear reactor. Why? Cadmium rods are given in nuclear reactors due to when we begin nuclear reactor then more energy is required for start the

How a CPH does stop or its speed decreases? Answer; it is a principle that Vc is stable thus that; gradV c =0 Thus, never V c increases or decreases.
