Explanation:
The equation that relates the intensity of an electromagnetic wave with the magnitude of the electric field is:
where
c is the speed of light
is the vacuum permittivity
E is the peak magnitude of the electric field
In this problem, we know the intensity:
I = 1600 W/m^2
So we can rearrange the formula to find E:
Answer:
Explanation:
From A to B
distance traveled with velocity in time
from B to C
distance traveled is 0.5 d with and
velocity for half-half time
divide 1 and 2 we get
Now average velocity is given by
taking common
