The amplitude of the oscillating magnetic field in the laser beam =2.28 x 10^-6 T
Given data
Power, P = 1.1 x 10^-3 W
Wavelength, λ = 633 x 10^-9 m
diameter, d = 1.5 x 10^-3 m
radius, r = 0.75 x 10^-3 m
Intensity of the beam = P / π r2
= 1.1 x 10^-3 W / π ( 0.75 x 10^-3m)2
= 622.47 W/m2
Equation for maximum electric feild
Emax = √ 2I / E0C
= √2 ( 622.47 W/m2) /( 8.85 x 10^-12 C^2 / N m2)(3.0 x 10^8 m/s)
= 684.76 V/m
The equation maximum magentic field is,
Bmax = Emax / c
= 684.76 V/m /3.0 x 10^8 m/s
=2.28 x 10^-6 T
The wavelength of a wave describes how lengthy the wave is. The distance from the "crest" (top) of 1 wave to the crest of the following wave is the wavelength.
Alternately, we can degree from the "trough" (bottom) of 1 wave to the trough of the subsequent wave and get the equal price for the wavelength.
