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 \[(\overset{\text{o}}{\mathop{\text{A}}}\,)\] Visible light 4000 - 7900 X-rays 1 - 100 Microwaves \[{{10}^{7}}-{{10}^{9}}\] Obviously, \[{{\lambda }_{x}}<{{\lambda }_{v}}<{{\lambda }_{m}}\] or \[{{\lambda }_{m}}>{{\lambda }_{v}}>{{\lambda }_{x}}\] Note: Visible light, X-rays and microwaves are all electromagnetic waves.
