Reflection and refraction are two of the ways light interacts with matter, with absorption being the third. Reflection occurs when incoming light is bounced off of a surface. Reflection can be either coherent, as it is with a mirror, or incoherent as when light reflects off of a white surface. Refraction entails the slowing and bending of light as it moves through a medium.Know More
The degree to which a surface reflects light is a measurable quality called albedo. The higher the albedo, the more incoming light the surface is able to reflect. Surfaces with low albedo usually absorb incoming light rather than reflect or refract it.
Refraction occurs as light transitions from one medium, such as air, to another such as glass or water. As they pass through the transparent substance, waves of light slow down or speed up depending on the density of the new medium. The various wavelengths of white light each slow at a different rate, which bends some wavelengths more than others. The result of this is that light passing through droplets of water suspended in a cloud or a glass prism in a laboratory can spread out into its constituent colors and form a rainbow.Learn more about Optics & Waves
Light interacts with matter through absorption, transmission and reflection. When light strikes the leaf of a plant, the leaf absorbs the light energy, and through the process of photosynthesis, transforms the energy into the food glucose. The leaf reflects the green wavelengths of visible light, giving it the green color.Full Answer >
Electromagnetic waves carry electromagnetic energy, also known as electromagnetic radiation, through matter, empty space, momentum and angular momentum. Depending on their frequency and wavelength, electromagnetic waves create different types of phenomena, including visible light, infrared radiation, ultraviolet radiation, radio waves, gamma rays, x-rays and microwaves.Full Answer >
Sound does not travel through a vacuum because molecules of matter are required for sound to exist, and vacuums do not have any matter. The vibrations and movements of small particles of matter are what create sound and allow it to be heard. In a vacuum without any matter, such as space, it is impossible for sound to travel.Full Answer >
According to TutorVista.com, waves carry energy through their up and down movements. The regular movements of the waves are able to carry two different types of energy: mechanical and electromagnetic. Some of these types of waves require certain types of environments and substances to travel through in order to move energy from one location to another.Full Answer >
