Constanta Part A If you use light of this wavelength, what would be the energy (in eV) of a single photon? To investigate the structure of extremely small objects, such as viruses, the wavelength of the probing wave should be about one-tenth the size of the object for sharp images. But as the wavelength gets shorter, the energy of a photon of light gets greater and could damage or destroy the object being studied. One alternative is to use electron...

A photon of wavelength 80 nm is absorbed by the electron in the groundstate level of the hydrogen atom. Is this enough energy to ionise the atom? If so calculate the kinetic energy of the free electron.

To investigate the structure of extremely small objects, such as viruses, the wavelength of the probing wave should be about one-tenth the size of the object for sharp images. But as the wavelength gets shorter, the energy of a photon of light gets greater and could damage or destroy the object being studied. One alternative is to use electron matter waves instead of light. Viruses vary considerably in size, but 50.0nm is not unusual. Suppose you want to study such...

a. Calculate the energy of a photon of electromagnetic radiation at 503 nm (wavelength of maximum solar radiation) and 337.1 nm (wavelength of nitrogen laser) b. Determine the wavelength of the light absorbed when an electron in a hydrogen atom makes a transition from an orbital in which n = 3 to an orbital in which n =6.

To resolve details of a cell using an ordinary microscope, you must use a wavelength that is about the same size, or smaller, than the details of the cell you want to observe. Suppose you wamt to be able to see the ribosomes, which are about 22.0 nm in diameter. If you use an electron microscope, what is the minimum kinetic energy of the electrons? eV
