In which region of the electromagnetic spectrum does the given wavelength fall in, has to be explained. Concept introduction: Spectroscopy: it is study of the interaction of matter and electromagnetic radiation, a continuum of different types of electromagnetic radiation each associated with a particular energy range makes up the electromagnetic spectrum. Electromagnetic radiation is defined as form of energy which is produced by oscillation of electric and magnetic interruption or by movement of electrically charged particles through vacuum. The frequency or wavelength range of electromagnetic radiation is called electromagnetic spectrum. Electromagnetic radiation: It is characterized as a wave is a by either its frequency ( ν ) or its wavelength ( λ ) .

Electromagnetic radiation is defined as form of energy which is produced by oscillation of electric and magnetic interruption or by movement of electrically charged particles through vacuum. The frequency or wavelength range of electromagnetic radiation is called electromagnetic spectrum.

Electromagnetic radiation: It is characterized as a wave is a by either its frequency (ν) or its wavelength (λ).

(b)

Interpretation Introduction

Interpretation:

It is advantageous to use light energy directly, as opposed to the heat energy of the sun to split water. This statement has to be explained.

Concept introduction:

• The difference in the heat energy which got absorbed during the breaking of bond and heat energy which got released during the formation of bond is known as the heat of reaction.

• Enthalpy(H): it is the total amount of heat in a particular system.

• Enthalpy change is another name for heat of reaction.

Regions of the Electromagnetic Spectrum 20. Use the pentagon shape at the bottom of the figure to slide along the spectrum. In the upper left corner you can see information about the wavelength and frequency of the radiation. Move the pentagon along the spectrum to help you fill in the blank spaces in the table below. You will need to calculate the energy column using the equation you gave in Question 19. The first one (gamma rays) has been done for you as an example.
