AP EAMCET2016PhysicsElectromagnetic Waves
Choose the correct sequence of the radiation sources in increasing order of the wavelength of electromagnetic waves produced by them.
Options
- AX-ray tube, Magnetron valve, Radioactive source, Sodium lamp
- BRadioactive source, X-ray tube, Sodium lamp, Magnetron valve
- CX-ray tube, Magnetron valve, Sodium lamp, Radioactive source
- DMagnetron valve, Sodium lamp, X-ray tube, Radioactive source
Correct answer
B. Radioactive source, X-ray tube, Sodium lamp, Magnetron valve
Step-by-step solution
The correct sequence of the radiation source in increasing order of the wavelength is Radioactive source ( 10⁻¹² ~m ) X-ray tube ( 10⁻¹⁰ ~m ) Sodium lamp ( 10⁻⁹ ~m ) Magnetron value ( 10⁻³ ~m ) .
