Light may be absorbed or scattered because of its interaction with: water itself, particulate matter suspended in the water, or dissolved chemicals (photolysis), especially dissolved organic matter.

We start with a discussion of the types of sources that emit visible light. Then we treat light as a classical wave and discuss reflection and refraction. Next we discuss polarization phenomena. We then …

The Physics of Light Any patch of light can be completely described physically by its spectrum: the number of photons (per time unit) at each wavelength 400 - 700 nm.

Jan 31, 2025 · Topics are addressed from a physics perspective and include the propagation of light in matter, reflection and transmission at boundaries, polarization effects, dispersion, coherence, ray …

Explain: Light travels at different speeds through different materials. When light rays pass from one medium to another, the difference in speeds between the two materials causes the ray to bend …

This subtractive color system uses colorants and reflected light. You start with an object that reflects light and use colorants (dyes or pigments) to subtract portions of the white light that is shining on the …

Light is an electromagnetic wave and doesn’t need a medium in which to travel. Electromagnetic waves can travel in a vacuum, as well as through materials such as air, water, and glass. What can you see …
