An X - ray tube produces a continous spectrum of radiation with its short wavelength end at `0.66 overset @A`.What is the maximum energy of a photon in the radiation?

An X-ray tube produces a continuous spectrum of radiation with its short wavelength end at 0.45 oversetcircA . What is the maximum energy of a photon in the radiation.

(a) An X-ray tube produces a continuous spectrum of radiation with its short wavelength end at 0.45 . What is the maximum energy of a photon in the radiation? (b) Form your answer to (a), guess what order of accelerating voltage (for electrons) is required in such a tube.

The wavelength of X-rays is 1 overset@A .Calculate its frequency.

Calculate the photon energy in electron- volt for radiation of wavelength 1 metre.

What voltage must be applied to an electron microscope to produce electrons of wavelength 0.4 overset @A ?

What voltage must be applied to an elecron microscope to produce electrons of wavelength 0.4 overset @A ?

Wavelength of electromagnetic radiation is doubled, what will happen to energy of photon?
