Wave Reflection, Absorption & Transmittance
Fun Facts
- Higher wavelengths produce brighter colors, and lower wavelengths produce darker colors.
- All waves have properties like wavelength, amplitude, and frequency.
- White light contains all colors and when the visible wavelength is reflected, that color is seen.
Why Do We Need To Know About Wavelength
Learning about wavelengths helps us understand how we can use the sun’s energy and why solar panels are important for green energy. This knowledge helps make solar panels better at turning sunlight into electricity.
Knowing about wavelengths is useful in many areas. It helps make better sound in music studios, create sunglasses that protect our eyes from bad UV rays, and even helps in making better camera lenses and glasses. Understanding wavelengths is important for lots of things in our everyday life and in making new technology.
