Your question: What is the most important electromagnetic spectrum?

The most important of these is visible light, which enables us to see. Radio waves have the longest wavelengths of all the electromagnetic waves. They range from around a foot long to several miles long.

What is the most important source of electromagnetic waves?

Answer 1: The most obvious source of electromagnetic energy and radiation is the sun. The sun provides the initial energy source for much of the remote sensing of the Earth surface. The remote sensing device that we humans use to detect radiation from the sun is our eyes.

What is the importance of electromagnetic spectrum?

Discovered more than a century ago, the electromagnetic spectrum is the basis on which our universe operates. Without it we wouldn’t be able to see, stars wouldn’t shine, and life would not exist. It is one of the most important principles that governs everything around us.

Which electromagnetic wave has the highest frequency?

Gamma rays have the highest energies, the shortest wavelengths, and the highest frequencies. Radio waves, on the other hand, have the lowest energies, longest wavelengths, and lowest frequencies of any type of EM radiation.

What is the source of all the waves in the electromagnetic spectrum?

Our Sun is a source of energy across the full spectrum, and its electromagnetic radiation bombards our atmosphere constantly. However, the Earth’s atmosphere protects us from exposure to a range of higher energy waves that can be harmful to life.

Which electromagnetic spectrum has lowest frequency?

The lowest frequency portion of the electromagnetic spectrum is designated as “radio,” generally considered to have wavelengths within 1 millimeter to 100 kilometers or frequencies within 300 GHz to 3 kHz.

Which type has the highest frequency?

Gamma rays have the highest frequency and the highest energy.

Which light has highest energy?

In our case of visible light, the highest frequency color, which is violet, which means it will have the highest energy.

What are the 4 main properties of electromagnetic waves?

Every form of electromagnetic radiation, including visible light, oscillates in a periodic fashion with peaks and valleys, and displaying a characteristic amplitude, wavelength, and frequency that defines the direction, energy, and intensity of the radiation.

Which part of the electromagnetic spectrum has largest penetrating power?

a) Part of the electromagnetic spectrum has largest penetrating power is Gamma Rays.
