Select the scientist connected with discovery of X-rays? Correct Answer Rontgen
CONCEPT:
- Electromagnetic spectrum: It is a collection of a range of different waves in sequential order from radio to gamma electromagnetic waves.
Properties of X-ray:
- X-rays are electromagnetic waves with a wavelength range 0.1Å – 100Å.
- The wavelength of X-rays is small in comparison to the wavelength of the light. Hence they carry more energy.
- They are invisible.
- They travel in a straight line with the speed of light.
- X-rays are measured in Rontgen (a measure of ionization power).
- X-rays carry no charge so they are not deflected in the magnetic field and electric field.
- They ionize gases.
- They produce a photoelectric effect and the Compton effect
- These cannot be used in Radar because they are not reflected by the target.
EXPLANATION:
- Wilhelm Conrad Roentgen discovered X-Rays in 1895. Therefore option 2 is correct.
- He discovered while working with a cathode-ray tube in his laboratory.
- The frequency of X-Rays is 1016 to 1019 Hz.
- X-rays are used to detect the cracks in bones, in medicine and industries, and also in security purposes.
