What are the types of light rays?

Answer 1

Do you mean the Six Categories of Light if so they are:

Highlight - area of object closest to the light source

- lightest area on the object

Light - next area of lightness

- area still in the path of the light source

Shadow - 1st area moving away from the light source

- starting to get darker

Core of Shadow - darkest area on the object

- area of object blocked from the light source

Reflected Light - small amount of light that reflects off of the table surface and back into the core of

shadow

Cast Shadow - are of the table surface blocked by the object

- light source cannot reach it, therefore, it is very dark

Answer 2

The different types of light are Ambient lighting: It lights each and every surface in the scene evenly. A very little amount of ambient lighting can be used to make a dim surface visible. Ambient light mimics the sun and fills a space with even amounts of light. Ambient lighting is generally useful in office and school settings.

Aesthetic lighting: This type of lighting can itself be described as a work of art. A neon sculpture would be purely decorative and an example of aesthetic lighting. A spotlight enlightening a statue on a pedestal or portrait on the wall is also artistic. This type of lighting also needs to be used along with other lighting types. Our widely popular Mood Light is the latest innovation in Aesthetic Lighting.

General lighting: It is considered to be the all-purpose type of lighting that creates a comfortable and safe environment. Generally, incandescent, fluorescent, halogen and other types of bulbs can provide this kind of Lighting from a wide variety of fixture types. The main consideration in General lighting is to provide an adequate level of light throughout the room without dark spots or shadows, as well as balancing the tone of the lights to work with other light sources.

Task lighting: This type of lighting is used to execute daily activities such as reading, cooking, shaving, putting on makeup, etc. It needs to be glare-free. Efficient task lighting enhances visual clarity and keeps the eyes from getting tired. Task lighting provides a direct beam of light for a specific task such as reading at a table.

Accent lighting: lighting to a particular direction or lighting that adds interest or highlights a certain object or unusual architectural feature in a room is accent lighting. A bulb and some kind of shield to direct the light are all that's needed for this type of lighting. Halogen spotlights and table lamps or floor lamps with opaque shades are good ways to achieve accent lighting.

Answer 3

There are four basic types of lighting: incandescent, fluorescent, high-intensity discharge, and low-pressure sodium 5. will be the solar light.

Incandescent

Incandescent lamps are the least expensive to buy but the most expensive to operate. Incandescent light is produced by a tiny coil of tungsten wire that glows when it is heated by an electrical current. Incandescent lamps have the shortest lives of the common lighting types. They are also relatively inefficient compared with other lighting types. However, significant energy and cost savings are possible if you select the right incandescent lamp for the right job. The three most common types of incandescent lights are standard incandescent, tungsten halogen, and reflector lamps.

Fluorescent

The most common type of lighting is fluorescent. These fixtures are more expensive as are the bulbs. However, the bulbs use less power than incandescent bulbs, and last longer. Fluorescent lighting is available in many different grades or intensities, including Normal Output (or N.O. or standard), Very High Output (or V.H.O.), and Power Compact. For all fluorescent lighting, the amount of light put out is a function of the length of the bulb and the type of bulb, so if two bulbs are the same length and for the same fixture, they put out the same amount of light.

High-Intensity Discharge

High-intensity discharge (HID) lamps provide the highest efficacy and longest service life of any lighting type. They are commonly used for outdoor lighting and in large indoor arenas.

HID lamps use an electric arc to produce intense light. They also require ballasts, and they take a few seconds to produce light when first turned on because the ballast needs time to establish the electric arc.

The three most common types of HID lamps are Mercury vapor, metal halide, and high-pressure sodium. HID lamps and fixtures can save 75% to 90% of lighting energy when they replace incandescent lamps and fixtures. Significant energy savings are also possible by replacing old mercury vapor lamps with newer metal halide or high-pressure sodium lamps.

Mercury vapor-the oldest type of HID lighting, is used primarily for street lighting. Mercury vapor lamps provide about 50 lumens per watt. They cast a very cool blue/green white light. Most indoor mercury vapor lighting in arenas and gymnasiums has been replaced by metal halide lighting, which has better color rendering and efficiency. Metal halide lamps are similar in construction and appearance to mercury vapor lamps. The addition of metal halide gases to mercury gas within the lamp results in higher light output, more lumens per watt, and better color rendition than from mercury gas alone. Metal halide lamps are used to light large indoor areas such as gymnasiums and sports arenas, and for outdoor areas such as car lots or anywhere that color rendition is important. High-pressure sodium lighting is becoming the most common type of outdoor lighting. It provides 90 to 150 lumens per watt, an efficiency exceeded only by low-pressure sodium lighting. High-pressure sodium lamps are also reliable and have long service lives. Their color is a warm white, and their color rendition ranges from poor to fairly good depending on design and intended use.

Low-Pressure Sodium

Low-pressure sodium lamps work somewhat like fluorescent lamps. They are the most efficient artificial lighting, have the longest service life, and maintain their light output better than any other lamp type. Low-pressure sodium lighting is used where color is not important because it renders all colors as tones of yellow or gray. Typical applications include highway and security lighting

Answer 4

The different types of lights are fluorescent, incandescent, outdoor solar, and light-emitting diode (LED) light. All these come from man made sources, but we can also find different types of light in nature, including visible, infrared and ultraviolet light.

Answer 5

fossil fuel (coal,oil,gas

solor energy

wind energy

geothermal energy

biomass energy

hydro sources of energy

Answer 6

Visible light rays are a very small part of the electromagnetic spectrum, ranging from very short gamma rays to very long infra red.

Answer 7

There are two main types of light rays: converging rays, which come together at a focal point after passing through a lens, and diverging rays, which spread out after passing through a lens.

Answer 8

Longitudinally & transverse
