Light can be reflected, transmitted and absorbed.

Transparent: transmits light Translucent: scatters light Opaque: absorbs or reflects all light that strikes it

Regular Reflection Parallel rays of light hit a smooth surface

Diffuse Reflection Also known as scattering Parallel rays of light hit a bumpy or uneven surface

Reflect Light

Plane Mirror Angle of Incidence equals the Angle of Reflection

Concave Mirror Brings parallel rays of light together

Convex Mirror Reflects parallel rays outward

Refract Light

Real images are those where light actually converges, whereas virtual images are locations from where light appears to have converged.

Virtual Image : an image formed when rays are perceived to meet Virtual images cannot be captured on a screen, because they are only formed by light rays APPEARING to have come from the same place. They always appear right-side up.

Real Image : an image in which perceived location is actually a point of convergence of the rays of light that make up the image. Real images can be captured on a screen. They are created by converging light rays, and always appear upside-down.

energy that can travel through space in the form of waves even when no matter is present

When the electric field changes (accelerates or decelerates) so does the magnetic field causing an electromagnetic wave. The accelerated electrons give off energy of varying wavelengths.

The Electromagnetic Spectrum All electromagnetic radiation travels at the same speed, but at different wavelengths
