A traveling electromagnetic wave in a vacuum has an electric field amplitude of 59.3 V/m. Calculate the intensity S of this wave
bija089 [108]

Answer: S = 4.67 W/m², U = 1.29 J

Explanation:

Given

Time of flow, t = 12.3 s

Area of flow, a = 0.0225 s

Amplitude, E = 59.3 V/m

Intensity, S = ?

I = E² / cμ, where

μ = permeability of free space

c = speed of light

E = E(max) / √2

E = 59.3 / √2

E = 41.93 V/m

I = 41.93² / (2.99*10^8 * 1.26*10^-6)

I = 1758.125 / 376.74

I = 4.67 W/m²

Energy that flows through

U = Iat

U = 4.67 * 0.0225 * 12.3

U = 1.29 J

Therefore, the intensity is 4.67 W/m² and the energy is 1.29J

What affect, if any, does increasing the speed of the plunger have on the wavelength of the waves
mojhsa [17]

As the speed of the plunger increases, the wavelength of the waves decreases. The greater the frequency, the smaller the wavelength. The smaller the frequency, the greater the wavelength. When we increase the speed of the plunger, the frequency of the waves also increases, and just like with the size of the ball, it’s the speed of the plunger and the frequency of the waves are directly related.

One of the primary visible emissions from a distant planet occurs at 425 nm. Calculate the energy of a mole of photons of this e
Stells [14]

Answer:

Explanation:

Given

Wavelength of incoming light \lambda =425\ nm

We know

speed\ of\ wave=frequency\times wavelength

frequency=\frac{speed}{wavelength}

\mu =\frac{3\times 10^8}{425\times 10^{-9}}

\mu =7.058\times 10^{14}\ Hz

Energy associated with this frequency

E=h\mu

where h=Planck's constant

E=6.626\times 10^{-34}\times 7.058\times 10^{14}

E=46.76\times 10^{-20}\ Hz

Energy of one mole of Photon=N_a\times E

=6.022\times 10^{23}\times 46.76\times 10^{-20}

=281.58\times 10^{3}

=281.58\ kJ
