X-Ray Scan
When X-rays move through the body, the EM wave is either absorbed or transmitted depending on its radiological density. The more radiation a medium absorbs, the lighter it looks.
CT Scan
X-Ray scans are taken at a range of angles around the object and then combined to form a 3D image.

Concave Lens
Diverging Lens
Convex Lens
Converging Lens
Converging Lens
Refracts light so the rays bend to a single point after moving through the lens.
Diverging Lens
Refracts light so the rays bend and spread out after moving through the lens.
Reflection
When part of the wave energy bounces off the interface and travels back into the original media
Refraction
The change in direction of an EM wave after passing through a new medium.
EM Spectrum
Relationship between wavelength, frequency and energy
As the wavelength decreases, the energy and frequency increase.
EM Wave
This kind of wave has both an electric and magnetic field with identical wavelength, period and frequency. It travels faster through less dense materials and can travel through a vacuum.
