Answer:
0.5
Explanation:
Data provided in the question:
The angle between their transmission axes, Īø = 60Ā°
Now,
We have the relation,
Iā = IācosĀ²Īø
where,
Iā is the intensity of the transmitted light
Iā is the intensity of the incident light
on rearranging, we get
[tex]\frac{I_1}{I_0}[/tex]=cosĀ²60Ā°
or
[tex]\frac{I_1}{I_0}[/tex]=0.5
Answer:
1/4
Explanation:
Let Iā be the intensity of polarised light from first polariser . After first polarisation, in the second polarisation, intensity changes as follows
I = Iā Ā CosĀ² Īøā°
I = Iā Ā CosĀ² 60ā°
= Ā Iā Ā 1 / 2Ā² = Iā / 4
So , 1/4 or one fourth of intensity from first polariser gets through the second polariser.
