A) \[{{\lambda }_{m}}>{{\lambda }_{x}}>{{\lambda }_{v}}\]
B) \[{{\lambda }_{v}}>{{\lambda }_{m}}>{{\lambda }_{x}}\]
C) \[{{\lambda }_{m}}>{{\lambda }_{v}}>{{\lambda }_{x}}\]
D) \[{{\lambda }_{v}}>{{\lambda }_{x}}>{{\lambda }_{m}}\]
Correct Answer: C
Solution :
Wavelength order of given rays are listed below: Rays Wavelength \[\mathbf{(}\overset{\mathbf{o}}{\mathop{\mathbf{A}}}\,\mathbf{)}\] Visible light \[4000-7900\] X-rays \[1-100\] Microwaves \[{{10}^{7}}-{{10}^{9}}\] Obviously, \[{{\lambda }_{x}}<{{\lambda }_{v}}<{{\lambda }_{m}}\] or \[{{\lambda }_{m}}>{{\lambda }_{v}}>{{\lambda }_{x}}\]
