Electromagnetic waves are often called "electromagnetic radiation".
That's a really strong clue.
Heat carried in the form of electromagnetic waves is radiation.
When the moon is between the sun and the earth.
We know, s = ut + 1/2gt²
In free-fall, u = 0
so, t = √2s/g
Now, substitute the values,
t = √2*4 / 9.8 [ -ve sign shows opposite direction only ]
t = √8/ 9.8
t = 0.90 sec
In short, Your Answer would be 0.90 sec
Hope this helps!
