Rays of light are produced when electromagnetic radiation, in the form of photons, are emitted or reflected from a light source such as the sun or a lightbulb. These photons travel in straight lines until they encounter a medium or surface that causes them to change direction, creating the perception of light rays.

What color is produced by the complete absorption of light rays?
Black is produced by the complete absorption of light rays. When an object absorbs all wavelengths of light and reflects none, our eyes perceive it as black.
How do gamma rays differ from light rays?
Gamma rays have much shorter wavelengths and higher frequencies than light rays, making them a form of high-energy electromagnetic radiation. Gamma rays are typically produced by radioactive decay or nuclear reactions, while light rays are composed of visible light across the electromagnetic spectrum. Gamma rays are more penetrating than light rays and can be harmful to living organisms.
What is virtual and real image?
A virtual image is formed when rays of light do not actually converge at the location of the image. It appears to be located behind the mirror or lens from which the rays of light are reflecting. A real image is formed when rays of light actually converge at the location of the image, making it possible to project it onto a screen.
How are real and virtual images produced?
Real images are produced by converging lenses when light rays actually converge at a point to form an image. Virtual images are produced by diverging lenses when light rays appear to converge at a point, but do not actually meet, resulting in an image that cannot be projected onto a screen.
How are Ultra-violet rays made?
Ultraviolet rays are produced naturally by the sun as part of its electromagnetic spectrum. They can also be produced artificially by specialized lamps or devices that emit UV light. UV rays are classified into three categories based on wavelength: UVA, UVB, and UVC.
What are the rays that are produced by the sunlight?
Rays that come from the sun are Ultraviolet rays (UV). You also get light rays and heat waves.
What color is produced by the complete absorption of light rays?
Black is produced by the complete absorption of light rays. When an object absorbs all wavelengths of light and reflects none, our eyes perceive it as black.
What colour produced as a combination of red green and black light rays?
Black isn't a light ray, its an absence of light. Red and green light assuming equal proportions makes yellow light

What are 5 different light waves that are produced in the universe that we can't see?
Five different light waves produced in the universe that we can't see include infrared radiation, ultraviolet light, X-rays, gamma rays, and radio waves. Infrared radiation is often associated with heat, while ultraviolet light can cause sunburn. X-rays and gamma rays are high-energy waves used in medical imaging and produced by cosmic events, respectively. Radio waves are used for communication and are emitted by various celestial objects, including stars and galaxies.
Is Compton effect reverse process of x-rays production?
No,The production of x rays is a reverse process of photoelectric effect. X rays are produced when target metal is bombarded by electrons while in photoelectric effect, the electron are produced when light waves are incident on a metal surface.
How are Ultra-violet rays made?

What type of mirrors can produced both converging and diverging rays?
Spherical mirrors, such as concave and convex mirrors, can produce both converging and diverging rays depending on the mirror's shape and orientation. Concave mirrors converge light rays to a focal point, while convex mirrors diverge light rays.
What is the name for the effect that is produced when warm air near earths surface bends light rays?
greenhouse effect
What is anomalous interference?
Anomalous interference colors are produced by dispersion of refractive indices from slow to fast light rays.
