Answer:
The answer is she will have to rotate the filter until the light's intensity is maximum. The light's polarization is along filter's axis.
Explanation:
This process is a phsycal phenomenon called the process of scattering of light by a molecule. We can also call it Rayleigh scattering.
Rayleigh scattering is used to explain why during daytime the sky looks so blue, the sunset looks so red, and the clouds so white. Polarization can also be explained by rayleigh scattering.
If a photographer wants to take a picture of the blue sky, she uses a polarizing filter to increase the ratio of the clouds' intensity of the blue sky.
To find the right direction, she will have to rotate the filter until the light's intensity is maximum. The light's polarization is along filter's axis.
Answer:
"Episodes (if applicable) and entries are usually alternated until the "final entry" of the subject, by which point the music has returned to the opening key, or tonic, which is often followed by closing material, the coda. In this sense, a fugue is a style of composition, rather than a fixed structure."
Answer:
Explanation:
<u>A: keystone </u>
Keystone is also known as capstone, <u>and it is the stone at the highest point of the arch construction.</u> It is placed as the final piece to lock the construction not to fall, as it is distributing the weight of the arch.
<u>B: voussoir</u>
<u>Voussoir is the name of the whole arched part,</u> including keystone and <u>impost</u>. It is the complete curved element, and the blocks included are most usually made out of stone.
<u>C: impost </u>
The impost is the name for the block that lies at the end of the column, a<u>nd it is also used for the block that is the start of the arch-shaped element</u> of the arch. It is the base of the voussoir.
D is the correct answer.
In the badly drawn diagram attached, you will find the <em>yellow</em> represents wavelength, which is the distance between identical points on consecutive waves.
The <em>green</em> represents the amplitude, which is the distance between the origin (middle) and crest/trough (top/bottom)
