When demonstrating the interference of light waves, the dark fringes that appear represent where the waves interfere ___________

skad [1K]

The dark fringes that appear represent where the waves interfere

C. Destructively

Explanation:

Interference is a phenomenon typical of waves, that occurs when two waves meet at a certain point in space. The amplitude of the resultant wave can be found by using the principle of superposition, which states that the displacement of the resultant wave is the sum of the displacements of each wave. In particular, there are two extreme cases that can occur:

- Constructive interference: this occurs when the two waves meet in phase - i.e., the crest of one wave meets with the crest of the other wave. In this case, the amplitude of the resultant wave is twice the amplitude of each wave.

- Destructive interference: this occurs when two waves meet in anti-phase - i.e, the crest of one wave meets with the trough of the other wave. In this case, the amplitude of the resultant wave is equal to the difference between the two amplitues (and if the two waves have same amplitude, the resultant amplitude will be zero).

This phenomenon can occur also with light wave (which is a type of wave), and it leads to:

- The presence of bright fringes in case of constructive interference

- The presence of dark fringes in case of destructive interference

Therefore, the correct answer is

C. Destructively

The doppler effect states that the motion of any object can ________

pshichka [43]

Answer:

shift the wavelength of spectral lines

Explanation:

The Doppler effect is commonly used in the field of astronomy to study the motion of astronomical objects such as a star, planets, and distant galaxies. This results in the changing of wavelength and shifting of the spectral lines, due to the relative and continuous motion of the receiver and the source. This is known as the red-shifting, where the lights in the spectrum move towards the highest wavelength, i.e towards the red light. This Doppler effect signifies that the distance between the distant galaxies and earth increases with the increasing recessional velocity.

The induced magnetic field at radial distance 4.0 mm from the central axis of a circular parallel-plate capacitor is 1.8 ✕ 10−7

wel

Answer:

$\frac{dE}{dt}=2.07*10^{13}\frac{V/m}{s}$

Explanation:

According to Gauss's law, the electric flux through the circular plates is defined as the electric field multiplied by its area:

$\Phi=EA=E(\pi R^2)(1)$

The magnetic field around the varying electric field of the circular plates is given by:

$B=\frac{\epsilon_0 \mu_o}{2\pi r}\frac{d\Phi}{dt}(2)$

Replacing (1) in (2) and solving for $\frac{dE}{dt}$ :

$B=\frac{\epsilon_0 \mu_o\pi R^2}{2\pi r}\frac{dE}{dt}\\\frac{dE}{dt}=\frac{2rB}{\epsilon_0 \mu_o R^2}\\\frac{dE}{dt}=\frac{2(4*10^{-3}m)(1.8*10^{-7}T)}{(8.85*10^{-12}\frac{C^2}{N\cdot m^2})(4\pi *10{-7}\frac{Tm}{A})(2.5*10^{-3}m)^2}\\\\\frac{dE}{dt}=2.07*10^{13}\frac{V/m}{s}$
