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 \[(\overset{o}{\mathop{A}}\,)\] |
Visible light | 4000-7900 |
X-rays | 1 - 100 |
Microwaves | \[{{10}^{7}}-{{10}^{9}}\] |
Obviously, | \[{{\lambda }_{x}}<{{\lambda }_{v}}<{{\lambda }_{m}}\] |
or | \[{{\lambda }_{m}}>{{\lambda }_{v}}>{{\lambda }_{x}}\] |
