A) 20 m
B) 200 m
C) 600 m
D) 60 m
Correct Answer: D
Solution :
[d] |
\[\theta =1.22\frac{\lambda }{a}\] |
Distance \[{{O}_{1}}{{O}_{2}}=\left( \theta \right)d\] |
\[=\left( 1.22\frac{\lambda }{a} \right)d\] |
\[=\frac{\left( 1.22 \right)\left( 5500\times {{10}^{-10}} \right)\times 4\times {{10}^{5}}\times {{10}^{3}}}{5}\] |
\[=5368\times {{10}^{-2}}m\] |
\[=53.68m\] |
