- Light waves interact with materials by being reflected, absorbed, or transmitted. Reflection occurs when a wave bounces off of a material. For example, a red piece of cloth may reflect red light to our eyes while absorbing other colors of light. Absorbance occurs when a material captures the energy of a light wave.

Dec 7, 2022 · Waves of Light. Light has the properties of waves. Like ocean waves, light waves have crests and troughs. The distance between one crest and the next, which is the same as the distance between one trough and the next, is called the wavelength.
Nov 14, 2024 · light, electromagnetic radiation that can be detected by the human eye. Electromagnetic radiation occurs over an extremely wide range of wavelengths, from gamma rays with wavelengths less than about 1 × 10 −11 metre to radio waves measured in metres.
Jun 15, 2019 · Key Concepts and Summary. Light waves interacting with materials may be reflected, absorbed, or transmitted, depending on the properties of the material. Light waves can interact with each other (interference) or be distorted by interactions with small objects or openings (diffraction).
Properties of Light. Recall that light travels in waves and that light is made up of particles are called photons. The length of the wave is measured from one peak to the next and is called the wavelength, which differs for different colors of light (Figure \(\PageIndex{2}\). Within the visible wavelengths of light, the longest wavelengths are ...

Dec 16, 2021 · What Is Light Energy? The sun emits an enormous amount of electromagnetic radiation (solar or light energy). Humans can see only a fraction of this energy, which is referred to as “visible light.” The manner in which solar energy travels is described as waves.

Light waves travel 299,792 km per second in a vacuum, (and somewhat slower in various media such as air and water), and those waves arrive at the eye as long (red), medium (green), and short (blue) waves. What is termed “white light” is light that is perceived as white by the human eye.
