Answer:
The most unique feature of “The Ninth” was that Beethoven included chorus and vocal soloists in the final movement. He was the first major composer to do this in a symphony.
Modern DSLR cameras use the Phase Detect autofocus method to determine the correct point at which to focus the lens. This method is fast and generally accurate, and operated by light travelling through the lens. When you half-press the shutter button on your DSLR while looking through the optical viewfinder, it’s Phase Detect autofocus that’s used.
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.
