Question

A Mencury Lamp is radiating monochnomatic
light of power
10 w The peak
value of electric
field strength at a distance of 5m from
The lamp is nearly.​

Answer 1

Answer:

, from equation 10, we can conclude that the amplitude of the electric field associated with the electromagnetic radiation at a distance of 5m from the lamp is nearly 2.68Vm−1. Hence, the correct answer is option B.
