Final answer:
The concept of orders in the context of wave interference.
Step-by-step explanation:
The question refers to the concept of orders in the context of wave interference. These orders describe the locations of maximum and minimum intensity in an interference pattern.
To find the order of a maximum or minimum, we use the equation:
x = m * λ * D / w
- x represents the distance from the central maximum (in meters)
- m is the order of the maximum or minimum
- λ is the wavelength of the wave (in meters)
- D is the distance between the source and the screen (in meters)
- w is the width of the obstacle (in meters)
