Describe the interference pattern produced from white light passing a single slit.
A bright central maximum surrounded by spectral fringes decreasing in intensity.
The inner edge of each spectral fringe is violet and the outer edge is red.

Describe what happens to light as it passes through a single slit?
Answer in your head, out loud, or on paper, then tap the card to flip.
What happens to the width of the central maximum if the slit width is increased?
The central maximum becomes narrower and more intense.

What is meant by a monochromatic light source?
Single frequency OR single wavelength
Lasers are an example of a monochromatic light source.

Compare the width of the central maximum to all other fringes in the single slit interference pattern.
The central maximum is twice as wide as all other fringes.

What is the equation linking the width of the central maximum (W), the wavelength of light (λ), width of single slit (a), and the distance to the screen (D)?
W = width of central maximum (m)
λ= wavelength (m)
D = distance to the screen (m)
a = single slit width (m)
