Electromagnetic Spectrum

Matter Review All matter is made of A______ Matter exists in different forms or phases. They are

Matter yes or no?

Electromagnetic spectrum Electromagnetic radiation (energy) that travels in waves and includes all the wavelengths

Types of Energy Light Magnetism Microwaves Radio X-rays All part of the electromagnetic spectrum

Anatomy of a wave

Wavelengths of visible light

How do we see color?

What does this have to do with electrons How do electrons travel within the electron cloud?

What does this have to do with electrons How do electrons travel within the electron cloud? Right-energy levels, so electrons have energy and we are going to find out that they emit (release) different amount of energies at different wavelengths so they have different colors

So, we did the chemicals burn different colors?
