Answer:
Explanation:
Given
Initial Intensity of light is S
when an un-polarized light is Passed through a Polarizer then its intensity reduced to half.
When it is passed through a second Polarizer with its transmission axis 

here 


When it is passed through third Polarizer with its axis
to first but
to second thus 



When middle sheet is absent then Final Intensity will be zero
Answer:
In biological taxonomy, a domain (also superregnum, superkingdom, or empire) is a taxon in the highest rank of organisms, higher than a kingdom. ... The three-domain system of Carl Woese, introduced in 1990, with top-level groupings of Archaea, Bacteria, and Eukaryota domains.
Answer:the force is needed to stretch it farther.
Explanation: the definition of force is push or pull so imagine stretching a rubber band your pulling the band which means you increase the force.
Answer:
from vacuum to air
Explanation:
Refraction is a property of lightwave, in which it changes speed as it passes the boundary between two media.
- When light travels from a denser medium to a less dense medium, the light wave speeds up and bends away from the normal.
- Also when light travels from a less dense medium to a denser medium, the light wave slows down and bends toward the normal.
The correct option must be from a less dense medium to a denser medium.
density of glass = 2500 kg/m³
density of air = 1.275 kg/m³
density of ice = 919 kg/m³
density of water = 1000 kg/m³
density of plastic = 940 kg/m³
density of vacuum = 6.5 x 10⁻²⁷ kg/m³
The two possible options are;
from ice to water
from vacuum to air
The difference in densities of ice and water is not larger compared to vacuum and air.
If you are required to choose two options, the two options are correct
But if it is only one option, then from vacuum to air is the correct answer.
Therefore, the correct option is from vacuum to air
