The speed of light is approximately 299,792 kilometers per second.
What is the electromagnetic spectrum?
The electromagnetic spectrum is the range of all types of electromagnetic radiation, including visible light.
What is reflection of light?
Reflection of light is the bouncing back of light when it hits a surface.
What is refraction of light?
Refraction of light is the bending of light when it passes from one medium to another.
What is the law of reflection?
The law of reflection states that the angle of incidence is equal to the angle of reflection.
What is the difference between transparent, translucent, and opaque objects?
Transparent objects allow all light to pass through, translucent objects allow some light to pass through, and opaque objects do not allow light to pass through.
What is the role of light in photosynthesis?
Light is absorbed by chlorophyll in plants during photosynthesis to convert carbon dioxide and water into glucose and oxygen.
What is the structure of the human eye?
The human eye consists of the cornea, pupil, lens, retina, and optic nerve.
What are the primary colors of light?
The primary colors of light are red, green, and blue.
What is the color wheel?
The color wheel is a circular chart that shows the relationship between colors. It consists of primary, secondary, and tertiary colors.
What is the difference between regular and diffuse reflection?
Regular reflection occurs when light waves strike a smooth surface and reflect at the same angle, while diffuse reflection occurs when light waves strike a rough or uneven surface and reflect in different directions.
What is the dual nature of light?
The dual nature of light refers to its ability to behave as both a particle (photon) and a wave.
What is the difference between incandescent and fluorescent light bulbs?
Incandescent light bulbs produce light by heating a filament inside the bulb, while fluorescent light bulbs produce light by passing an electric current through mercury vapor inside the bulb.
What is total internal reflection?
Total internal reflection occurs when light waves in a denser medium strike the boundary of a less dense medium at an angle greater than the critical angle, causing all the light to be reflected back into the denser medium.
What is the principle of superposition?
The principle of superposition states that when two or more light waves overlap, the resulting wave is the sum of the individual waves.
What is the relationship between light frequency and color?
Higher frequencies correspond to bluer colors, while lower frequencies correspond to redder colors.
