Study Notes
Electromagnetic Waves and Properties
- Red light has the lowest frequency among the visible spectrum.
- Sound is not an electromagnetic wave; it is a mechanical wave.
- Some electromagnetic waves can pass through walls that light cannot penetrate.
- X-rays differ from visible light primarily by wavelength.
Young's Double-Slit Experiment
- A single slit ensures a constant phase relationship for light waves to form an interference pattern.
- For visible light, frequency and wavelength vary with color.
Light Composition and Color Perception
- Incandescent bulbs emit all visible wavelengths of light.
- Ultraviolet light reflecting off a violet surface appears black, as violet absorbs similar wavelengths.
- Red light has a greater wavelength than green light, while blue light has a greater frequency than green light.
Color Mixing and Perception
- Adding red and green light produces yellow.
- A surface illuminated by magenta light that absorbs red will appear blue.
- The primary color needed to create white light from magenta is green.
Human Vision and Atmospheric Effects
- The normal human eye can detect colors from 400 nm to 700 nm wavelengths.
- Blue skies are due to the atmosphere scattering blue light more efficiently.
Wave Properties and Behavior
- Electromagnetic waves in the air travel as transverse waves and do not require a medium.
- The relationship between wave speed (v), wavelength (λ), and frequency (f) follows the equation v = fλ.
- The correct speed of light in air is approximately 3 x 10^8 m/s.
Interference and Diffraction
- Interference occurs when two light waves combine, creating areas of reinforcement and cancellation.
- Light can cause diffraction, allowing some light to be seen in geometric shadows of narrow slits.
- A thin oil layer produces colored patterns due to light interference at both oil/air and oil/water interfaces.
Polarization and Optical Devices
- Polarization of light is determined by the direction of the oscillating electric field.
- Polaroid material is commonly used to polarize beams of light, often in sunglasses.
- Applying an anti-reflective coating on glass increases light transmittance.
Light Behavior and Environmental Interaction
- Under green light, a green surface appears green; plants do not effectively utilize green light.
- Diffuse reflection occurs when light reflects off surfaces irregularly, reducing shine.
- Unpolarized light passing through a polarizing filter results in about half being polarized.
Color Models and Vision Components
- Subtractive color mixing uses magenta, yellow, and cyan as primary colors.
- Cones are the light-sensitive cells in the human eye responsible for color vision.
- Infrared waves have shorter wavelengths compared to microwaves, an essential understanding in light spectrum.
Summary of Reflection and Interference
- Mirrors produce specular reflection, allowing for distinct images.
- When light passes through a diffraction grating, blue fringes appear closer to the central bright spot than red fringes.
