What are the properties of colors of light?

The colours of visible light are red, orange, yellow, green, blue, indigo, and violet. These different colours of light have different wavelengths and frequencies. Red light has the longest wavelength, and the lowest frequency of the visible spectrum.

What are the properties of light Class 8?

(i) Light is a form of energy, which includes the sensation of vision in our eyes and make us able to see various things present in our surrounding. (ii) When light falls on an object, some part of light is reflected back to our eyes. Then, we are able to see an object because of light being reflected from the object.

What are the three basic properties of light?

waves in various parts of the electromagnetic spectrum (including visible light, infrared, and ultraviolet radiation). It is essential for students to know the basic properties of light, including brightness, colors, and being visible.

What are the important properties of color?

Properties of ColorHue: Hue is the name of a pure color, such as red, blue, or yellow.Value: Value is the lightness or darkness of a hue (color). The value of a hue can be changed by adding black or white. … Intensity: Intensity is the brightness or dullness of a hue (color). Pure hues are high-intensity colors.

What is light short answer?

Light is a form of electromagnetic radiation with a wavelength which can be detected by the human eye. It is a small part of the electromagnetic spectrum and radiation given off by stars like the sun. … Light exists in tiny energy packets called photons. Each wave has a wavelength or frequency.

What are the 3 properties of Colour?

Color Attributes And every color can be described in terms of having three main attributes: hue, saturation and brightness. Hue is identified as the color family or color name (such as red, green, purple).

What are the color of white light?

The spectrum of white light consists of six basic colours arranged in a specific order: red, orange, yellow, green, blue and violet. Although Newton understood that a beam of light of a particular colour is always deviated by the same amount, he did not appear to understand why this is so.

What are the properties of lights?

Light is electromagnetic radiation that has properties of waves. The electromagnetic spectrum can be divided into several bands based on the wavelength. As we have discussed before, visible light represents a narrow group of wavelengths between about 380 nm and 730 nm.
