Gamma rays
have the highest energies and shortest wavelengths on the electromagnetic spectrum.
What is the largest part of the electromagnetic spectrum?
Radiation that has both electric and magnetic fields and travels in waves
. It comes from natural and man-made sources. Electromagnetic radiation can vary in strength from low energy to high energy. It includes radio waves, microwaves, infrared light, visible light, ultraviolet light, x-rays, and gamma rays.
Which part of the electromagnetic spectrum is the most useful?
Infrared (IR) radiation
– also referred to as thermal radiation – is the portion of the electromagnetic spectrum lying between visible light and microwaves. The most important natural source of infrared radiation is the sun.
Which part of the electromagnetic spectrum has the largest highest frequencies?
Gamma rays
have the highest energies, the shortest wavelengths, and the highest frequencies.
Which part of the electromagnetic spectrum is the fastest?
Gamma rays
have the highest frequency. Radio waves have the longest wavelength. None of those present has the highest speed. All photons travel at the same speed, at the speed of light, regardless of energy.
What are the 7 types of radiation?
The electromagnetic spectrum includes, from longest wavelength to shortest:
radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays

Which color has the highest energy?
Your brain interprets the various energies of visible light as different colors, ranging from red to
violet
. Red has the lowest energy and violet the highest.
What color has the highest frequency?
Violet
waves have the highest frequencies.
What letter has lowest frequency?
He found the smallest numbers of J, X, and Z. In modern Morse code,
J, Y, and Q
are least frequent.
What color in the electromagnetic spectrum has the most energy?
Red has the lowest energy and
violet
the highest.
What is the fastest form of light?
- Gamma rays.
- Visible light.
- None of these; they all travel at the same speed.
- X-rays.
- Radio waves.
Which waves has the highest speed?
Gamma rays have the highest frequency. Radio waves have the longest wavelength.
None
of those present has the highest speed. All photons travel at the same speed, at the speed of light, regardless of energy.
What part of the electromagnetic spectrum can we see?
The visible light spectrum
is the segment of the electromagnetic spectrum that the human eye can view. More simply, this range of wavelengths is called visible light. Typically, the human eye can detect wavelengths from 380 to 700 nanometers.
What is the weakest type of radiation?
Alpha rays
are the weakest and can be blocked by human skin and gamma rays are the strongest and only dense elements like lead can block them.
What are the three major types of radiation?
The three most common types of radiation are
alpha particles, beta particles, and gamma rays
. Alpha radiation is not able to penetrate skin.
What are the 5 types of radiation?
- electromagnetic radiation, such as radio waves, microwaves, infrared, visible light, ultraviolet, x-rays, and gamma radiation (γ)
- particle radiation, such as alpha radiation (α), beta radiation (β), proton radiation and neutron radiation (particles of non-zero rest energy)
