A) 64 : 127
B) 1 : 2
C) 64 : 27
D) None of these
Correct Answer: D
Solution :
According to Rayleigh scattering formula Intensity of scattered light \[I\propto \frac{1}{{{(\lambda )}^{4}}}\propto {{f}^{4}}\] \[\therefore \] \[\frac{{{f}_{1}}}{{{f}_{2}}}={{\left[ \frac{{{I}_{1}}}{{{I}_{2}}} \right]}^{1/4}}\] \[={{\left[ \frac{256}{81} \right]}^{1/4}}\] \[=\frac{4}{3}\] Hence, option [d] is correct.You need to login to perform this action.
