Light is a form of electromagnetic radiation, which is a wave phenomenon. It consists of oscillating electric and magnetic fields that propagate through space.

The speed of light in a vacuum is approximately 3 x 10^8 meters per second, which is one of the fundamental constants of the universe.

The frequency and wavelength of light are inversely proportional, meaning that as the frequency increases, the wavelength decreases, and vice versa.

Refraction is the bending of light as it passes from one medium to another, such as from air to water or from glass to air.

Reflection is the bouncing back of light from a surface, such as a mirror or a wall.

Absorption is the process by which light is taken in and converted into other forms of energy, such as heat or chemical energy.

Scattering is the process by which light is redirected in different directions due to interactions with particles, such as dust or water droplets.

There is no single primary color of light. The concept of primary colors is related to the human visual system and the way it perceives different wavelengths of light.

Complementary colors are pairs of colors that, when combined, produce white light. The complementary color of red is green.

Complementary colors are pairs of colors that, when combined, produce white light. The complementary color of blue is orange.

Complementary colors are pairs of colors that, when combined, produce white light. The complementary color of yellow is purple.

Diffraction is the bending of light around an obstacle or through an aperture, resulting in the spreading out of light waves.

Interference is the superposition of two or more light waves, resulting in the enhancement or cancellation of light intensity at specific points.

Polarization is the restriction of light waves to a single plane of vibration, resulting in the alignment of the electric field vector.

Dispersion is the separation of light into its component colors, such as red, orange, yellow, green, blue, indigo, and violet, due to the different wavelengths of light being refracted at different angles.
