Chapter 11, Problem 4A

Interpretation Introduction

Interpretation: The similarity and difference of different electromagnetic radiation needs to be explained

Concept introduction: Electromagnetic radiation is the form of radiation that is produced by oscillation of electric and magnetic field line disturbance in vacuum.

Answer to Problem 4A

Similarity between different electromagnetic radiation is they travel at speed and difference is because of difference in wavelength and energy.

Explanation of Solution

The different types of electromagnetic radiation that is radio waves, microwaves, infrared, ultraviolet rays and X-ray have the same speed that is 3,00,000km/sec.

And difference between these electromagnetic radiations is energy which is inversely proportional to wavelength.

  $\begin{array}{l}\text{E}\propto \frac{\text{1}}{\text{λ}},\text{where}\text{E}\text{is}\text{energy}\\ \text{λ}\text{is}\text{wavelength}\end{array}$

Conclusion

Radiation provides an important means of energy transfer.
