Light waves are a special kind of electromagnetic wave. This means they are part of a bigger group called the electromagnetic spectrum.

The electromagnetic spectrum includes different types of waves that vary in size and speed.

Key Points:

• Electromagnetic Waves: These waves are made of moving electric and magnetic fields. They travel through space at an incredible speed, which is about 299,792,458 meters per second, or simply the speed of light!

• Wavelength and Frequency: Light waves have sizes, or wavelengths, that range from about 400 nanometers (nm) to 700 nm. If you want to find out the frequency, which tells us how often the wave goes up and down, you can use this simple formula:

  $f = \frac{c}{\lambda}$

  In this formula:

  • ( f ) is the frequency,
  • ( c ) is the speed of light,
  • ( \lambda ) is the wavelength.

• Position in the Spectrum: The electromagnetic spectrum has many types of waves. It includes gamma rays, X-rays, ultraviolet light, visible light, infrared light, microwaves, and radio waves. Visible light, which we can see, falls between ultraviolet (which has shorter waves) and infrared (which has longer waves).

Summary:

In short, light waves are an important part of the electromagnetic spectrum. They help us understand the special nature of light and how it connects to other types of electromagnetic waves.
