What are the 7 types of electromagnetic spectrum?

What are the 7 types of electromagnetic spectrum?

The electromagnetic spectrum includes, from longest wavelength to shortest: radio waves, microwaves, infrared, optical, ultraviolet, X-rays, and gamma-rays.

What are the 7 electromagnetic waves in order?

In order from highest to lowest energy, the sections of the EM spectrum are named: gamma rays, X-rays, ultraviolet radiation, visible light, infrared radiation, and radio waves.

Which electromagnetic waves enable humans?

Visible light waves are the only electromagnetic waves we can see. We see these waves as the colors of the rainbow. Each color has a different wavelength.

What 3 ways do we describe waves and what are the units that go with these terms?

Electromagnetic radiation can be expressed in terms of energy, wavelength, or frequency. Frequency is measured in cycles per second, or Hertz. Wavelength is measured in meters. Energy is measured in electron volts.

What are the Colour of the spectrum?

The visible spectrum

colour* wavelength (nm) energy (eV)
red 650 1.91
orange 600 2.06
yellow 580 2.14
green 550 2.25

What are the types of radiation?

There are four major types of radiation: alpha, beta, neutrons, and electromagnetic waves such as gamma rays. They differ in mass, energy and how deeply they penetrate people and objects.

What are the colors in the color spectrum?

The visible spectrum

colour* wavelength (nm) frequency (1014 Hz)
red 650 4.62
orange 600 5.00
yellow 580 5.16
green 550 5.45

How EM waves are produced?

Electromagnetic radiation is, classically speaking, a wave of electric and magnetic fields propagating at the speed of light c through empty space. In this wave the electric and magnetic fields change their magnitude and direction each second.

Is light invisible or visible?

The human eye can only see visible light, but light comes in many other “colors”—radio, infrared, ultraviolet, X-ray, and gamma-ray—that are invisible to the naked eye. On one end of the spectrum there is infrared light, which, while too red for humans to see, is all around us and even emitted from our bodies.

Is light mechanical or electromagnetic?

Light waves are different from mechanical waves, however, because they can travel through a vacuum. Light waves are just one type of electromagnetic wave. Other electromagnetic waves include the microwaves in your oven, radio waves, and X-rays.

What is difference between longitudinal and transverse wave?

In a longitudinal wave, the displacement of the particles happens parallel to the direction the wave travels. In contrast, the displacement of particles in the transverse wave is perpendicular to the direction the wave is travelling.

How are EM waves wavelength and frequency related?

Section Summary. The relationship among the speed of propagation, wavelength, and frequency for any wave is given by vW = fλ, so that for electromagnetic waves, c = fλ, where f is the frequency, λ is the wavelength, and c is the speed of light.
