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 (\[{\AA}\]) |
| 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. |
