Final answer:
This High School Physics question is about the double-slit interference pattern created by light with wavelengths of 500-nm and 650-nm passing through two slits 0.50 mm apart and projecting onto a screen 2.0 m away.
Step-by-step explanation:
The subject of this question is Physics, specifically related to wave optics and the phenomenon known as two-slit interference or Young's double-slit experiment. This question falls under the High School level, as it involves understanding and applying the principles of light interference patterns created by waves passing through slits, which are typically covered in high school physics curricula.
The experiment in question involves a beam with light wavelengths of 500-nm and 650-nm illuminating two slits that are 0.50 mm apart, and the interference pattern is projected on a screen 2.0 m away. To solve problems like this, students must use equations that relate the slit separation, the distance to the screen, the wavelengths of the light, and the resulting interference pattern on the screen.
