A beam of polarized light with an average intensity of 13.5 W/m² is sent through a polarizer. The transmission axis makes an angle of 22.0° with respect to the direction of polarization. Determine the rms value of the magnetic field of the transmitted beam.

Brms = (2.205 × 10⁻⁷) T

Explanation:

The relationship between rms magnetic field and the intensity of the electromagnetic wave is given as

I = (Erms × Brms)/μ₀

where Erms = rms Electric field of the electromagnetic beam

Brms = rms magnetic field of the electromagnetic beam

μ₀ = magnetic constant = (4π × 10⁻⁷) H/m

But Erms is related to Brms through the relation

Erms = c × Brms

where c = speed of light = (3 × 10⁸) m/s

And the intensity of polarized light (I) is related to the initial intensity of polarized light (I₀), through the relationship

I = I₀ cos² θ

where θ = angle the transmission axis makes with respect to the direction of polarization = 22.0°

I₀ = initial intensity of unpolarized light = 13.5 W/m²

I = (Erms × Brms)/μ₀ becomes

I₀ cos² θ = (c × Brms²)/μ₀

Brms² = (μ₀ × I₀ cos² θ)/c

Brms² = (4π × 10⁻⁷ × 13.5 × cos² 22°)/(3 × 10⁸)

Brms² = 4.861 × 10⁻¹⁴

Brms = 0.0000002205 = (2.205 × 10⁻⁷) T

Hope this Helps!!!

electromagnetic waves travel through space with vacuums. give me brainliest if right.

the total distance that martina travels that day is

(distance from home to mom's office) plus (distance from mom's office to school)

plus (distance from school to library) plus (distance from library to friend's house)

plus (distance from friend's house to martina's house).

(we don't know what any of these distance actually is.)
