Answer:
This is an attempt to more clearly visualize the nature of single slit diffraction. The phenomenon of diffraction involves the spreading out of waves past openings which are on the order of the wavelength of the wave.
Explanation:
Answer:
a. It always points perpendicular to the contact surface.
Explanation:
"Normal" means perpendicular. Normal forces are always perpendicular to the contact surface.
Explanation:
Given that,
Frequency of the power line, f = 6 Hz
Value of maximum electric field strength of 11.6 kV/m
(a) The wavelength of this very low frequency electromagnetic wave is given by using relation as :
![c=f\lambda](https://tex.z-dn.net/?f=c%3Df%5Clambda)
![\lambda=\dfrac{c}{f}](https://tex.z-dn.net/?f=%5Clambda%3D%5Cdfrac%7Bc%7D%7Bf%7D)
![\lambda=\dfrac{3\times 10^8\ m/s}{60\ Hz}](https://tex.z-dn.net/?f=%5Clambda%3D%5Cdfrac%7B3%5Ctimes%2010%5E8%5C%20m%2Fs%7D%7B60%5C%20Hz%7D)
![\lambda=5\times 10^6\ m](https://tex.z-dn.net/?f=%5Clambda%3D5%5Ctimes%2010%5E6%5C%20m)
(b) As its can be seen that the wavelength of this wave is very high. It shows that it is a radio wave.
(c) The relation between the maximum magnetic field strength and maximum electric field strength is given by :
![B_0=\dfrac{E_0}{c}\\\\B_0=\dfrac{11.6\times 10^3}{3\times 10^8}\\\\B_0=3.86\times 10^{-5}\ T](https://tex.z-dn.net/?f=B_0%3D%5Cdfrac%7BE_0%7D%7Bc%7D%5C%5C%5C%5CB_0%3D%5Cdfrac%7B11.6%5Ctimes%2010%5E3%7D%7B3%5Ctimes%2010%5E8%7D%5C%5C%5C%5CB_0%3D3.86%5Ctimes%2010%5E%7B-5%7D%5C%20T)
So, the maximum magnetic field strength is
.
