Geometric and Physical Optics: Interference and Diffraction

(Originais Teachy 2023) - Question Easy of Physics

Interference of waves is a phenomenon that occurs when two or more waves meet and interfere with each other. The result of wave interference depends on the behavior of the waves, whether they add up or cancel out. When two waves of the same frequency and same direction meet, they add up, resulting in what is called constructive interference. However, when two waves of the same frequency and opposite direction meet, they cancel out, resulting in what is called destructive interference. What is the result of the interference between two waves of the same frequency and opposite direction?
a.
The doubling of the amplitude of those two waves.
b.
The addition of those two waves.
c.
A new type of wave with different characteristics.
d.
The tripling of the frequency of those two waves.
e.
The cancellation of those two waves.

In Young's Experiment, also known as the diffraction of light by a double slit, two beams of light are emitted through two narrow and parallel slits, creating an interference pattern alternating between bright and dark bands on a screen located at a distance 'L' from the two slits. Knowing that the slits are separated by a distance 'd', the wavelength of light is őĽ, and the angle of inclination between the central point (line of maxima) and a point of maxima (n-th maximum) is őł, determine the position 'yn' of the n-th interference maximum on the screen. Use the formula: sinőł = nőĽ/d.

On a summer morning, a central radio station broadcasts radio waves at two different frequencies for communication with maritime vessels. The first wave has an amplitude of 2m, a wavelength of 20m, and the crests move at a speed of 8m/s, while the second wave has an amplitude of 3m, a wavelength of 30m, and the crests move at a speed of 12m/s. When these two waves meet at a certain point, they are in phase and wave superposition occurs. Considering this scenario, answer: (a) What is the amplitude of the resulting wave? (b) What is the phase difference between the two waves in this situation? (c) If the phase difference were 180¬į, what would be the amplitude of the resulting wave?

Imagine a situation where you have two bar magnets. The first magnet has its North pole facing the South pole of the second magnet. You know that the magnetic field lines emerge from the North pole and enter the South pole. Now, you decided to place a small iron nail midway between the two magnets. In which direction will the iron nail align itself in response to the magnetic field lines present at its location, and why?
