trichromatic: Having or involving three colours. The human eye, for example, responds to three colours (red, green and blue) and their related hues.

Colors oflightGrade 7

White light is made up of light with a range of different wavelengths known as the visual spectrum. Every colour that we can see has a different wavelength and energy.

What is coloroflightin science

rod: A rod-shaped light receptor on the retina responsible for vision in low light conditions that does not contribute greatly to colour detection.

Artificial rainbows can be created in class by shining a light source through a prism or clear glass of water — the same process occurs as in raindrops of a rainbow seen outside.

Why do colours have different wavelengths

electromagnetic radiation: Waves of energy that are both electric and magnetic. A certain range of electromagnetic radiation has wavelengths that we recognize as visible light.

This unit also demonstrates numerous ways of producing or revealing colour through chemical reactions, mixing different colours of light and pigments, and chromatography. As a result, students develop an appreciation for the complexity of something we take for granted: colour!

Ordinarily, light waves vibrate in every plane and direction. Polarized light is light that is only vibrating in one plane. A polarizing lens permits only light vibrating in one plane to pass through. Polarizing lenses are used in cameras and sunglasses to block the horizontal solar glare that is produced on reflective surfaces, such as lakes.

Identify colour change as one of the possible outcomes of a chemical reaction. Describe how different colours of light mix to form new colours. Perform methods to “separate” colours. Explain how polarizing filters work and their use in our daily lives.

polarizer: A device that converts a beam of light that is oscillating (moving back and forth at a regular speed) in different directions into just one plane. An example of a polarizer is sunglasses.

Rods respond to all wavelengths of the visible spectrum in low light conditions; that is, they allow us to see objects in dim lighting conditions.

In this series of demonstrations and activities, students will explore how colours are created and understood by our brain.

wavelength: The distance between the peak or crest of a wave of light, heat or other energy and its next crest; the length of one wave.

Cones, on the other hand, respond to very specific wavelengths, and are responsible for sending colour information to the brain. There are three different types of cone receptors for coloured light: one is most sensitive to red light, one to green light, and one to blue light. With these three colour receptors we are able to distinguish millions of colours. Cones are less sensitive than rods; they require higher levels of light to function. This is why it is difficult to make out the colour of objects in low light conditions.

visible spectrum: The range of all the visible wavelengths of light, including all the colours of the rainbow: red, orange, yellow, green, blue, indigo and violet.

CMOS and CCD surveillance cameras are often designed withonly minimal night vision range or sometimes without infrared LEDs at all. This high-power spotlight will add or increase your existing surveillance cameras infrared viewingrange of up to 50 metres. The six built-in LEDs switch on automatically at night or when dark conditions are detected.The compact size of the spotlight is ideal where unobtrusivesurveillance in low light areas is preferred, such as warehouses, driveways, backyards, alleyways and boundary line fences. Includes a 12VDC power supply and mounting hardware. Features: • Automatic day/night operation • Weatherproof • 180° Bracket Adjustment Specifications: Infrared LEDs: 6 x 3W Infrared wavelength: 850nm Infrared Angle: 60° Effective Infrared Range: up to 50m IP Rating: IP65 Power Supply: 12VDC, 1.5A Dimensions: 165(L) x 84(Dia)mm

the human eye can detect only three colors of light.whatthree colors are they?

In order to see colours, there must be at least a little bit of light. White light is actually made of all colours, but the colours you see depend on the amount and colour of light being reflected (thrown back) or absorbed (taken in) by an object.

whattermisused to describe the bending oflightwaves as it moves through different environments?

A rainbow is formed when white light passes through rain droplets. Since the different colours contained in white light have different wavelengths, they are refracted through the droplets at different angles, and the colours are thus separated.

polarize: To cause both the electric and magnetic fields associated with electromagnetic waves, especially light waves, to vibrate in a particular direction or path.

A red apple looks red because white light, either from light bulbs or from the sun, hits its surface, and all of the colours are absorbed except the red which is reflected back to your eye. The cones on your retina get “excited” when they are hit by red light and send electrical signals to your brain, which then recognizes the apple as red.
