A thin layer of oil (n = 1.38) on the ocean surface for thousands of miles. As an inspector, you are flying over the ocean surfa
ce in an aircraft, looking at a section of option where the oil thickness is 563 nanometers thick. You look straight down at the ocean, at a time of day when the sun is directly above you. a) So, if constructive interference occurs (i.e. where the reflection is brightest) what is the wavelength(s) of visible light in the reflection? b) However, in order to get a close-up look at the oil slick, you put on scuba gear and go diving under the portion of ocean you had been observing from the plane. For which wavelength(s) of visible light yield the strongest transmitted intensity?

Answer:
q = 2.65 10⁻⁶ C
Explanation:
For this exercise we use Coulomb's law
F =
In this case they indicate that the load is of equal magnitude
q₁ = q₂ = q
the force is attractive because the signs of the charges are opposite
F =
q =
we calculate
q =
q = Ra 7 10-12
q = 2.65 10⁻⁶ C
This question involves the concepts of echo, ultrasonic images, ultrasonic sound waves.
The process of ultrasonic images uses the "echo" property of the sound waves.
Echo is the property of the sound wave by the virtue of which the sound wave reflects back to the source of the sound after hitting a surface or an object.
Ultrasonic images are obtained from inside organs of our body. This process involves the use of ultrasonic sound waves that have a frequency greater than 20,000 Hz. These sound waves are out of the range of audible sound by the human ear. When these ultrasonic sound waves are sent in form of pulses into the human body by the use of probes, they reflect back from the tissues of different organs to the probe. The probe then records the reflection properties of these sound waves and displays them in form of an image, known as ultrasonic images.
