State the uses of electromagnetic radiations.

The terminology of different parts of the electromagnetic spectrum is given in the text. Use the formula E = h ν (for energy of a quantum of radiation: photon) and obtain the photon energy in units of eV for different parts of the electromagnetic spectrum. In what way are the different scales of photon energies that you obtain related to the sources of electromagnetic radiation?

Electromagnetic Wave or Radiation

(a) State three important properties of photons which describe the particle picture of electromagnetic radiation. (b) Use Einstein's photoelectric equation to define the terms (i) stopping potential and (ii) threshold frequency.

Which is not electromagnetic radiation?

Define the term "Intensity" in photon picture of electromagnetic radiation.

For the study of the helical structure of nucleic acids, the property of electromagnetic radiation generally used is
