Q: If two coherent sources of light are in phase, what type of interference pattern will be observed?

Solution: When two coherent sources are in phase, they produce constructive interference, resulting in bright fringes.

Steps: 5

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 it means for the sources to be in phase. When two sources are in phase, their peaks and troughs align perfectly.
Step 3: Learn about interference. Interference occurs when two waves meet and combine their effects.
Step 4: Identify the type of interference. When the waves from the two sources are in phase, they create constructive interference.
Step 5: Recognize the result of constructive interference. This results in bright fringes or bands of light on a screen.
