₹0.0

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

Options:

Correct Answer: Constructive interference

Solution:

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

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

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.

Coherent Sources – Coherent sources are light sources that maintain a constant phase relationship, leading to predictable interference patterns.
Interference Patterns – Interference patterns arise from the superposition of waves, resulting in regions of constructive and destructive interference.
Constructive Interference – Constructive interference occurs when waves are in phase, leading to increased amplitude and bright fringes in the observed pattern.
