5.2 Waves and Wavelengths — How Your Brain Decodes Light and Sound Waves | Psychology 2e
After this lesson you will be able to…
- Learn the physical properties of waves: amplitude (force) and frequency (rate of oscillation).
- Discover the inverse relationship between a wave's physical length and its frequency.
- Explore how different light wavelengths trigger receptors to create our perception of color.
- Understand the narrow range of light wavelengths humans can perceive compared to other species.
- Learn how sound wave frequency determines pitch and the limits of human hearing.
- Understand how sound wave amplitude dictates intensity, perceived as volume, measured in decibels.
- Discover how timbre, the purity of sound, allows us to distinguish different instruments.
