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
Explore the aspects of electromagnetic spectrum, focusing on the visible light spectrum. Learn to identify colours, describe dispersion of light through prisms, and explain wavelengths related to colours.
