One day, after pulling down your window shade, you notice that sunlight is passing through a pinhole in the shade and making a small patch of light on the far wall. Having recently studied optics in your physics class, you're not too surprised to see that the patch of light seems to be a circular diffraction pattern. It appears that the central maximum is about 3 cm across, and you estimate that the distance from the window shade to the wall is about 3 m.

Estimate the average wavelength of the sunlight (in nm).

Respuesta :

Answer:

The average wavelength of the sunlight is 550 nm

Explanation:

The average wavelength of the sulight is:

[tex]\lambda _{ave}=\frac{\lambda _{i}+\lambda _{f}}{2}[/tex]

λi = initial wavelength of the sun = 400 nm

λf = final wavelength of the sun = 700 nm

Replacing:

[tex]\lambda _{ave}=\frac{400+700}{2} =550nm[/tex]
