Answer:
The answer will be A. Wedge
Explanation:
Infrared radiation from young stars can pass through the heavy dust clouds surrounding them, allowing astronomers here on Earth to study the earliest stages of star formation, before a star begins to emit visible light. Suppose an infrared telescope is tuned to detect infrared radiation with a frequency of 1.61THz. Calculate the wavelength of the infrared radiation. Round your answer to 3 significant digits.
Answer:
λ = 1.86 x 10⁻⁴ m = 186 μm
Explanation:
The relationship between the wavelength and the frequency of a wave is given by the following equation:
[tex]c = f\lambda\\\\\lambda = \frac{c}{f}[/tex]
where,
λ = wavelength of infrared radiation = ?
c = speed of infrared radiation = speed of light = 3 x 10⁸ m/s
f = frequency of infrared radiation = 1.61 THz = 1.61 x 10¹² Hz
Therefore,
[tex]\lambda = \frac{3\ x\ 10^8\ m/s}{1.61\ x\ 10^{12}\ Hz}[/tex]
λ = 1.86 x 10⁻⁴ m = 186 μm

A transparent oil with index of refraction 1.15 spills on the surface of water (index of refraction 1.33), producing a maximum of reflection with normally incident violet light (wavelength 400 nm in air). Assuming the maximum occurs in the first order, determine the thickness of the oil slick.
Answer:
The thickness of the oil slick. t = 173.91 nm
Explanation:
Oil film thickness t is given by the equation
[tex]t = \frac{\lambda}{2n}[/tex]
where λ = wavelength of incident light in air = 400 nm
and n = index of refraction of oil
therefore,
[tex]t =\frac{400}{2\times 1.15}\\t= 173.91 nm[/tex]
The thickness of the oil slick. t = 173.91 nm
Types of telescope
for Space
observation
Answer:The three main types are reflecting telescopes, refracting telescopes, and catadioptric telescopes. Radio telescopes collect and focus radio waves from distant objects. Space telescopes orbit Earth, collecting wavelengths of light that are normally blocked by the atmosphere.

Explanation:
According to Lenz's law, the current is induced in the closed conducting loop in such a direction that the magnetic field induced by this current opposes the change in the flux through the loop.
a. True
b. False
Answer:
True
Explanation:
It is true that the real definition of lenz's law in magnetism is the current is induced in the closed conducting loop in such a direction that the magnetic field induced by this current opposes the change in the flux through the loop.
This means that induced current opposes the very cause that produces it.

for her situation. She is currently complaining of crying episodes, not eating, headaches, thinking she is a failure,
spending most of her time in bed, and not being interested in activities she once enjoyed doing with her kids, such as
going to the park and seeing movies. Her mother and grandfather also showed signs of mental illness and she
reported that her mom has taken Depakote before, which helped. Sarah wants to open her own restaurant and move to
a bigger house.
1. Please answer the following questions by referring to the above case study and the assigned reading for this
unit:
• What psychological and physical symptoms does Sarah present with?
. What is the primary psychological disorder diagnosis that fits her symptoms based on the disorders
described in the textbook?
Answer:
how to deal with devoirce
Explanation:
The psychological and physical symptoms that Sarah presents include:
She frequently has headaches.She also has a loss of appetite.She gets angry easily.From the information given, we can infer that some of the symptoms include the fact that Sarah frequently has headaches, loss of appetite, and gets angry easily.
The primary psychological disorder diagnosis that fits her symptoms based on the disorders will be depression. She's depressed because she just got divorced. This has taken a toll on her health.
