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

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 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.

Coherent Sources – Coherent sources are light sources that maintain a constant phase relationship, leading to predictable interference patterns.
Interference Types – Interference can be constructive (bright fringes) or destructive (dark fringes) depending on the phase relationship of the waves.
Constructive Interference – Constructive interference occurs when waves are in phase, resulting in increased amplitude and brightness.
