On a sunny summer day, the intensity of sunlight at the earth's surface is about 1000 w/m2. what are the peak electric and magnetic fields in this sunlight?

peak value of magnetic field is

peak value of electric field is

Explanation:

As we know that the intensity of electromagnetic waves is given by the formula

here we have

now we have

now peak value of electric field is given as

So the peak value of electric field is given as

Now we have relation between electric field and magnetic field as

potential energy is directly proportional to height.

more height = more potential energy.

greatest increase in height = greatest increase in potential energy

where are the points with the greatest increase in height ?

has to be c-e or d-e .

blue light is scattered in different directions by the tiny molecules of air. blue is scattered more than other colours because it has a shorter distance to travel which results in smaller waves. this is why we see a blue sky most of the time.
