Answer:
the percentage of light that gets through this combination is 9.38
Explanation:
Given the data in the question;
Let us represent the incident unpolarized light with .
So, the amount of light intensity passing through the first polarizer will be;
= / 2 ------ let this be equation 1
An the amount of light intensity passing through the second polarizer will be;
= cos²θ
given that; the second one has its transmission axis at 30°
so, we substitute;
= × cos²( 30° )
= × 0.75
= 0.75
from equation; = / 2
= 0.75( / 2 )
= 0.375 .
Now, the amount of light intensity passing through the third polarizer will be;
= cos² ( 90° - 30° )
= × cos²( 60° )
= × 0.25
we substitute
= 0.375 × 0.25
= 0.09375
∴ / × 100 = 0.09375 × 100
⇒ 9.38%
Therefore, the percentage of light that gets through this combination is 9.38
Answer:answer is part a 100 x
Explanation:
We know that a prefix of Mega(M) is used for a quantity of
numbers thus 100 MW = 100 x
Answer:
13.335 CM (1 ft, 1.335 cm)
I am 80% sure this is the answer, but i am not too keen on math so if i am wrong let me know and i will try my best to fix it!
I hope this helped! Have a good day :]
