Study Notes
Colors of White Light
- White light consists of seven main colors: Red, Orange, Yellow, Green, Blue, Indigo, Violet.
- Order of colors by decreasing wavelength:
- Red > Orange > Yellow > Green > Blue > Indigo > Violet
- Order of colors by increasing energy and frequency:
- Violet > Indigo > Blue > Green > Yellow > Orange > Red
Relationship Among Frequency, Energy, and Wavelength
- Frequency and energy are directly related, while frequency and wavelength are inversely related.
- Higher frequency means higher energy and shorter wavelength.
- Lower frequency corresponds to lower energy and longer wavelength.
Refraction and Dispersion of Light
- Rainbows are formed by the dispersion of white light through a prism.
- Different colors bend at different angles due to varying refractive indices.
- Violet light bends the most, while red light bends the least.
Visual Spectrum and Wavelengths
- Visible spectrum shows light in the range of 380-750 nm.
- Shorter wavelengths (e.g., violet) have higher frequency and energy, while longer wavelengths (e.g., red) have lower frequency and energy.
- Index of refraction varies among colors:
- Violet (1.530) > Indigo (1.526) > Blue (1.524) > Green (1.519) > Yellow (1.518) > Orange (1.514) > Red (1.512)
Key Concepts Related to Light Behavior
- Refraction occurs when light moves between media of different optical densities.
- Light slows down and changes direction when entering a denser medium, leading to bending towards the normal.
- White light can be separated into its component colors through a prism due to differences in speed and wavelength.
Questions and Concepts
- Highest frequency and energy color: Violet.
- Longest wavelength color: Red.
- Incorrect statement about wavelength and frequency: Short wavelength corresponds to low frequency.
- Color between blue and violet: Indigo.
- Color that bends the most: Violet, which has the highest refractive index.
Conclusion
- Understanding the behavior of light, including refraction and dispersion, is key to comprehending natural phenomena like rainbows and the visible spectrum.
- The relationship between wavelength, frequency, and energy is fundamental in physics, particularly in understanding electromagnetic waves.
