In this question we have three parts so let's start with the first part.
00:05
In the first part we can say that the magnetic field amplitude of the magnetic field amplitude of wave is we can write bm which is equal to em divided by c so it becomes 2 divided by 3.
00:33
Multiplied by 10 to power 8.
00:35
So on a simplification, it becomes a 6 .7, multiplied by 10 to power minus 9, tesla.
00:42
So this is the first answer of this question, that is the magnetic field amplitude of the wave.
00:48
Now, in the second part, we can write the intensity.
00:54
The intensity is i, which is equals to em square, divided by 2 mu note c so we can write it as 2 square divided by 2 multiplied by 4 pi multiplied by 10 to power minus 7 multiplied by 3 multiplied by 10 to power 8 so on a further simplification we get this value of intensity i which is equals to 5 .3 multiplied by 10 to power minus 3 what per meter square...
