## Homework Statement

Monochromatic light of wavelength 592 nm from a distant source passes through a slit that is 0.0290 mm wide. In the resulting diffraction pattern, the intensity at the center of the central maximum (θ = 0∘) is 3.00×10−5 W/m2 .

What is the intensity at a point on the screen that corresponds to θ = 1.20∘?

Express your answer with the appropriate units.

## Homework Equations

$$I = I_0[\sin(\pi*a*\sin(\theta)/\lambda)/(\pi*a*\sin(\theta)/\lambda)]^2$$

## The Attempt at a Solution

I used the formula and values and got an answer of 1.13*10^-9 W/m^2 but it says it's incorrect and I'm not sure why.
