If coherent light with a wavelength of 400 nm flows through two incredibly small slits separated by 0.200 mm, the interference pattern results in a first-order brilliant fringe that is 8.0 mm wide (in millimeters).

What is a wavelength?

Wavelength is the separation between point q (adjacent crests) in successive cycles of a wave signal traveling through space or over a wire. In wireless systems, its length is typically expressed in meters (m), centimeters (cm), or millimeters (mm).

How do you measure wavelength?

Any two corresponding spots on adjacent waves can be measured to determine the wavelength. In the case of a wave motion, a wavelength determination is obtained by determining the separation between one compression and the next or between one rarefaction and the next.
