Question

source of sinusoidal electromagnetic waves radiates uniformly in all directions. At a distance of 10.0 m from this source, the amplitude of the electric field is measured to be 3.50 N>C. What is the electric-field amplitude 20.0 cm from the source

Explanation:

= Initial electric field = 3.5 N/C

= Final electric field

= Initial distance = 10 m

= Final distance = 20 cm

Electric field is given by

So,

The electric field amplitude at the required point is .
