What is the electromagnetic spectrum?

• consists of all the different wavelengths of electromagnetic energy, including radio waves, microwaves, infrared light, visible light, ultraviolet light, X-rays, and gamma rays.

• Spectrum produced by the emitted radiation

• When sunlight is passed through a prism, it gets dispersed into continuous bands of different colors

• all of this is part of the EM spectrum

Why do all types of electromagnetic energy not reach the Earth’s surface?

• All types of EM energy do reach Earth's surface.

• Our atmosphere blocks out harmful energy like X-rays, gamma rays and most ultraviolet rays, infrared, and low energy radio waves

• No EM energy can penetrate through Earth's surface.

• Gamma rays are the only energy that can't reach the surface.

In which list are forms of electromagnetic energy arranged in order from longest to shortest wavelength?

• Microwave -> Radio wave -> Infrared rays

• Visible light -> x-ray -> radio wave

• Microwave -> infrared -> visibile light

• Infrared -> radio wave -> ultraviolet
