Answer:
The intensity is 0.559.
Explanation:
Given that,
Angle = 58.0°
The intensity at the peak of the central maximum is I₀
We need to calculate the intensity
Using formula of intensity
[tex]I=I_{0}\cos^2(\dfrac{\phi}{2})[/tex]
Where, I = intensity
[tex]I_{0}[/tex]=maximum intensity
Put the value into the formula
[tex]\dfrac{I}{I_{0}}=\cos^{2}(\dfrac{58.0}{2})[/tex]
[tex]\dfrac{I}{I_{0}}=0.559[/tex]
Hence, The intensity is 0.559.
