Assignment Help:

Find amplitude of electric field ina parallel beam of light of intensity 2W/m2

Ans:

Given that intensity I=power/area=2W/M2

by using this formula :intensity I=(Emax^2/2c mue not)

from that Emax=magnitude of electric field

c=velocity of light=3*10^8m/sec

mue not =4pi*10^-7

Emax=38.82 N/m
