Electromagnetic Radiation

Electromagnetic waves are waves that can travel through space without needing a medium such as air or water. They include radio waves, microwaves, inf

The electromagnetic spectrum is the full range of electromagnetic waves, from very long radio waves to extremely short gamma rays. Each part of the sp

Electromagnetic waves travel through space at the speed of light, which is about 300,000 kilometers per second. These waves have two important propert

When electromagnetic radiation, such as light, interacts with matter, it can behave in different ways depending on the material it hits. Light can be

Electromagnetic waves are all around us, even though we can only see a small part of them—visible light. These waves don’t need air or any other matte

Light is a special kind of energy because it behaves in two different ways—it acts like a wave and also like a particle. This is known as the dual nat

Radio waves are a type of electromagnetic wave that we can’t see, but we use them every day. They help carry signals for radios, TVs, cell phones, and

Radio waves are the longest waves in the electromagnetic spectrum. They travel through the air at the speed of light and are used to carry signals ove

Microwaves are a type of electromagnetic wave with shorter wavelengths than radio waves but longer than infrared waves. They travel at the speed of li

Microwaves are a type of electromagnetic wave used in many areas of daily life and technology. Because they can pass through materials like glass and

Sunlight may look white, but it’s actually made up of different types of light that travel as waves. These include visible light, which you can see, a

Gamma rays are the most energetic type of electromagnetic radiation. They have the shortest wavelengths and the highest frequencies in the electromagn

X-rays are a type of high-energy light that you cannot see with your eyes. They are part of the electromagnetic spectrum, like visible light and ultra

X-rays are a powerful type of invisible light that can travel through some materials but not others. This special ability makes X-rays very useful in
