DEEP THOUGHTS, WITH MRS. LEEVER...

I CAN… Apply an understanding of electromagnetic spectrum to the composition and movement of objects in space.

WHAT IS THE ELECTROMAGNETIC SPECTRUM? The entire range of electromagnetic waves with different frequencies and wavelengths. It includes: 1.gamma rays 2.x-rays 3.ultraviolet waves 4.visible light 5.infrared waves 6.Microwaves 7.radio waves

SO WHAT IS A WAVE? In this diagram the white line represents the position of the medium when no wave is present, (like a rope tied to something at one end). The yellow line represents the position of the medium as a wave travels through it.

SO WHAT IS A WAVE?

Amplitude is how high above, or low beneath the center line the wave gets.

SO WHAT IS A WAVE? Wavelength (also symbolized as Λ or lambda) is the distance from peak to peak, trough to trough, or from where the wave hits the first time to the third time).
