Quantum Chemistry
Quantum chemistry deals with the properties of chemical systems and their reactions. The branch of chemistry which is more concerned with quantum chemistry is physical chemistry. It is a more sophisticated field of theoretical physics which is concerned …

Chapter 7.1, Problem 7.1BFP
Interpretation Introduction

Interpretation:

The frequency of a 940 nm radiation wavelngth is to be calculated. Also the type of electromagnetic radiation is to be determined.

Concept introduction:

Electromagnetic waves are radiations that are formed by oscillating electric and magnetic fields. The electric and magnetic field components of an electromagnetic wave are perpendicular to each other. The general properties of electromagnetic waves are as follows:

1) Electromagnetic waves travel at the speed of light.

2) Electromagnetic waves are transverse in nature.

3) Electromagnetic waves may be polarized.

4) Electromagnetic waves are not deflected by electric or magnetic field.

5) Electromagnetic waves need no medium for propagation.

The formula to relate the frequency and wavelength of an electromagnetic radiation is,

υ=cλ (1)

Here, υ and λ are the frequency and wavelength of the electromagnetic radiation respectively and c is the speed of light.
