Electromagnetic Spectrum – Sample Questions
Question 1: What are electromagnetic waves?
Answer:
Electromagnetic waves are vibrations made up of perpendicularly oscillating electric and magnetic fields.
Question 2: What are the frequency and wavelength of an EM wave of energy 6.626 x 10-19 J?
Answer:
Frequency(f) = E/h
= 1015 Hz.
Wavelength(λ) = c/f
= 3 x 108 / 1015
= 3 x 107 m
Question 3: What is Spectroscope?
Answer:
Spectroscopy is the study of how light and other electromagnetic radiation are emitted and absorbed by matter based on the wavelength or frequency of the energy.
Electromagnetic Spectrum
Electromagnetic Spectrum: The sun is our planet’s principal source of energy, and its energy travels in the form of electromagnetic radiation. Electromagnetic energy moves across space at the speed of light in the form of waves of electric and magnetic fields with a range of frequencies or wavelengths.
Electromagnetic radiation is a common occurrence in our daily lives. All electromagnetic waves, from visible light, that our eyes can detect to microwave radiation that heats our meals or radio waves that power our radios, X-rays that enable doctors to identify any injury in our bones, or UV radiation emitted by a hot surface, are EM waves.
In this article, we have provided all types of electromagnetic radiation in the Electromagnetic Spectrum, their properties, diagrams, and applications of Electromagnetic Spectrum.
