Question

$100\mathrm{\pi }$ phase difference $=$ ………. path difference.

• A. $10\lambda$
• B. $25\lambda$
• C. $50\lambda$
• D. $100\lambda$

Answer 1

The correct option is C

$50\lambda$

Step 1 Given data

$Phasedifference=100\mathrm{\pi }$

Step 2. Finding the value of the path difference.

By using the formula of Path difference,

$Pathdifference=\frac{\lambda }{2\mathrm{\pi }}\times Phasedifference$

$Pathdifference=\frac{\lambda }{2\mathrm{\pi }}\times 100\mathrm{\pi }$

$Pathdifference=50\lambda$

Hence, the correct option is $\left(C\right)$.
