What are conditions for a bright and a dark fringe?

Bright fringes occur when the path difference between two waves is a whole number of wavelengths, leading to constructive interference. Dark fringes occur when the path difference is a half-integer multiple of the wavelength, resulting in destructive interference.


What is the difference between Riemann and Lebesgue integral?

The Lebesgue integral covers a wider variety of cases. Specifically, the definition of hte Riemann integral permits a finite number of discontinuities; the Lebesgue integral permits a countable infinity of discontinuities.

What is the number of wavelengths in a given unit of time?

The number of wavelengths in a given unit of time is determined by the frequency of the wave. It is equal to the frequency of the wave multiplied by the duration of time. Mathematically, it can be expressed as: Number of wavelengths = Frequency x Time.
