Name the part of electromagnetic spectrum, which is used in greenhouse to keep the plants warm.

Which constituent radiation of the electromagnetic spectrum is used: for taking photographs of the sky during night and foggy conditions? Give one reason for your answer

The terminology of different parts of the electromagnetic spectrum is given in the text. Use the formula E = hv (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?
