Question

In a single slit diffraction experiment, how does the angle to the first dark fringe depend on the wavelength of the light used?

Answer 1

In a single slit diffraction experiment, the angle to the first dark fringe depends on the wavelength of the light used. The angle is given by the equation θ = (λ / w), where θ is the angle, λ is the wavelength of the light, and w is the width of the slit.

Step-by-step explanation:

In a single slit diffraction experiment, the angle to the first dark fringe depends on the wavelength of the light used. The angle is given by the equation θ = (λ / w), where θ is the angle, λ is the wavelength of the light, and w is the width of the slit.

For example, if the wavelength of the light used is 530 nm and the width of the slit is 1.5 μm, the angle to the first dark fringe can be calculated as follows:

θ = (530 nm / 1.5 μm) = 354°
