Cont.

• won the Nobel Prize in physics

• X-ray spectroscopy 1924

• X rays-to determine energies that bind electrons to atoms

• 1950s turned his attention to electron spectroscopy

Facts about X-Rays

• Wavelength of approx. 10nm to 0.001nm

• X-ray detectors collect photons of X-ray light

• X-rays were first reckindised in 1895

• X-rays can't travel through metal

X-Ray at Hospital

• X-ray sensitive film on 1 side of body

• X-rays are shot through you

• Make you wear a coat jacket

• Look at Broken Bones

X-Rays at the Dentist

• film in mouth on 1 side of teeth

• X-rays are shot through jaw

• just like a picture

• Does not hurt can't feel X-rays.

Nobel Prize

• 1913 began series of experiments

• led discoveries of M series of X rays

• demonstrated the shell arrangement of electrons within atom

• developed equipment, techniques that established X-ray spectroscopy

Cont.

• awarded 1924 Nobel Prize for Physics

• later served (1937–64)

• director of Nobel Institute of Physics in Stockholm

• Won it for X-ray spectroscopy

X-ray spectroscopy

• basic applications of X-ray analysis:• Diffraction X-rays on crystalline to

obtain crystal structure• Measurement of energy emitted X-

rays during SEM imaging• X-rays knock out electrons to

provide surface chemical
