Answer:
f = frequency = 590,000 Hz ===> 59×10^4 Hz
λ = Wavelength = ?
c = Speed of light in a vacuum = 3 × 10^8 m/s
** Hz = 1/sec

Answer:
If it is pure, the substance is either an element or a compound. If a substance can be separated into its elements, it is a compound. If a substance is not chemically pure, it is either a heterogeneous mixture or a homogeneous mixture. If its composition is uniform throughout, it is a homogeneous mixture.
Given what we know, we can confirm that if you aimed light from the magenta part of the Horsehead Nebula through a spectrograph we would be able to determine more precisely the structure and details of the cloud.
<h3>How do we use Spectrums in order to understand stars?</h3>
The spectrums recorded by scientists, such as those of stars or nebulas like the horsehead nebula can tell us a great deal about the composition of said entities. Studying the spectrum can tell scientists about the chemical composition of stars or nebulas, such as information about the elements that form them, like their temperatures and densities.
<h3 /><h3>How would a discontinuous emission of hydrogen gas look in the spectrum?</h3>
This would appear as pauses in the lines of the spectrum. If the emission of the hydrogen gas were constant, there would be a continuous line on the spectrum graph to indicate the illuminated hydrogen, though if this line were discontinuous, we would be able to assume that its source is emission from another gas instead.
Therefore, we can confirm that spectrography is an essential part of scientific discovery pertaining to our universe. It allows us to study the chemical composition of stars and nebulas, and determine the sources of certain emissions like that of hydrogen gases.

Answer:
Because they convert the electrical voltage produced by increasing and then it goes into the power lines
Explanation:
