A) \[\Rightarrow \]
B) \[\frac{1}{2}m{{v}^{2}}=eV\]
C) \[\Rightarrow \]
D) None of these
Correct Answer: A
Solution :
Light passing through a material of thickness d is attenuated by absorption and scattering. The exponential law of absorption gives the relation as \[\frac{1}{9x}=\frac{1}{60R-x}\] where \[\Rightarrow \] is wavelength. Alternative: The option (b) and (c) are dimensionally incorrect while option (a) is dimensionally correct.You need to login to perform this action.
