Study Notes
Wavelengths of Light
- Red light possesses the longest wavelength in the visible spectrum.
- Violet light has the shortest wavelength among visible colors.
Color Perception
- Objects appear a certain color by absorbing all colors except the one they reflect.
- The color perceived is based on the light that reflects off an object.
Types of Waves
- Mechanical waves require a medium for propagation (e.g., sound waves).
- Electromagnetic waves can travel through a vacuum and are produced by vibrating charged particles.
Wave Characteristics
- The wave crest is the highest point of a wave.
- The amplitude measures the distance from the midline to the crest or trough.
- A wave trough refers to the lowest point of a wave.
Energy and Color
- Violet light has the highest energy and frequency, while red has the lowest.
- Energy and frequency correlate directly; higher energy means higher frequency.
- Energy and wavelength are inversely related; higher energy results in shorter wavelengths.
- Frequency and wavelength have an inverse relationship; higher frequency corresponds to shorter wavelength.
Refraction
- Violet light refracts the most due to its shorter wavelength and higher frequency.
- Red light refracts the least because of its longer wavelength and lower frequency.
Electromagnetic Spectrum
- Waves to the left of the visible light spectrum (e.g., radio, microwaves) have shorter wavelengths, higher frequencies, and higher energy.
- Waves to the right (e.g., infrared, ultraviolet) have longer wavelengths, lower frequencies, and lower energy.
Order of Waves
- Longest to Shortest Wavelength: Radio, Microwave, Infrared, Visible Light, Ultraviolet, Gamma Rays.
- Shortest to Longest Wavelength: Gamma Rays, Ultraviolet, Visible Light, Infrared, Microwave, Radio.
Color Frequency Order
- From highest to lowest frequency: Violet, Blue, Green, Yellow, Orange, Red.
- From lowest to highest frequency: Red, Orange, Yellow, Green, Blue, Violet.
- Wavelength comparison: Violet < Blue < Green < Yellow < Orange < Red.
Refraction and Medium
- Refraction occurs when a wave changes direction passing from one medium to another.
- As light travels from gas to liquid, its speed decreases and bends more.
- When moving from liquid back to gas, light speed increases and bends less.
Light Phenomena
- Reflection occurs when light bounces off an object.
- Dispersion explains the spreading of white light into the spectrum's colors.
- Scattering happens when light passes through an imperfect medium.
Additional Wave Properties
- Wavelength is defined as the distance between two consecutive wave troughs or crests.
- Comparisons between colors: Red has a longer wavelength than green and blue; Blue has higher frequency and energy than red.
Important Formulas
- The wavelength can be calculated using the formula: wavelength = speed of light / frequency.
Wave Comparisons
- Radio waves have a longer wavelength than visible light, while gamma waves have a higher frequency than visible light.
- Radio waves are longer than both ultraviolet and gamma wavelengths.
