Study Notes

Electromagnetic Spectrum

Ranking system of electromagnetic radiation from weakest (longest wavelength) to strongest (shortest wavelength)
Includes: Radio, Microwaves, Infrared, Visible Light, UV, X-ray, and Gamma Rays

Visible Spectrum

Small part of the electromagnetic spectrum
Only visible part of the spectrum
Consists of ROYGBIV (Red, Orange, Yellow, Green, Blue, Indigo, Violet)
Enables us to see what is around us

Dispersion of Light

Occurs when white light passes through a glass prism and splits into the colors of the visible light spectrum
Light hits the prism and refracts (bends)

Key Points about Light

Transparent: All light passes through
Translucent: Some light passes through
Opaque: No light passes through

Refraction and Reflection

Refraction: Process of light bending through a medium
Mirrors reflect, not refract light
