If two coherent sources of light are in phase, what type of interference will occur?
Correct Answer: Constructive interference
- Step 1: Understand what coherent sources are. Coherent sources are light sources that have a constant phase difference and the same frequency.
- Step 2: Know what 'in phase' means. When two light waves are in phase, their peaks and troughs align perfectly.
- Step 3: Learn about interference. Interference occurs when two or more waves overlap and combine.
- Step 4: Identify the type of interference. When the waves are in phase, they combine to make a larger wave.
- Step 5: Conclude that this is called constructive interference, which results in bright fringes.
