Calculating the Distance Between Two Slits Using Interference
Understanding the Phenomenon of Interference:
To understand the equation, we must consider the phenomenon of interference. When a wavelength of light passes through two slits, it creates two waves that interfere with each other. The bright lines on the screen occur when the two waves are in phase, and the dark lines occur when the waves are out of phase.
Explanation of the Equation:
The distance between the bright lines on the screen is equal to one wavelength of the laser light multiplied by the ratio between the distance between the two slits and the distance between the two slits and the screen.
Interference is a key concept in understanding optics and the behavior of light. By studying the patterns created by passing light through double slits, we can gain insights into the wave nature of light and the phenomenon of interference.
