Wavelengths of different colour of light

In summary, the conversation discusses an experiment where different colored lights from the same source were used to shine on a beaker of water, resulting in varying rates of temperature increase. It is mentioned that red light raises the temperature higher than blue light, and the question is asked about the wavelength of the different colors of light. A link is provided for further information on visible light and its different colors.

Hey guys
Today I've done an experiment and I found that when different color of light from the same light source (put of different color filter on the same light source) shine on a beaker of water, the temperature of the water will rise.

And different light will rise the temp of water in different rate. Such as red light will rise the temperature higher than the blue light, but here is the question

May I know that the wavelength of different colur of light?
Thanks

Look up visible light on wikipedia. It should give you approximate ranges for each color.

Well the use infra red for heating stuff don't they.
The longer waves seem to work best.
 

Related to Wavelengths of different colour of light

1. What is the relationship between wavelength and color of light?

The wavelength of light refers to the distance between two consecutive peaks or troughs of a light wave. Each color of light has a specific wavelength, with shorter wavelengths corresponding to colors on the blue end of the spectrum and longer wavelengths corresponding to colors on the red end of the spectrum.

2. How are different colors of light produced?

The colors of light that we see are produced by the different wavelengths of light that are emitted or reflected by objects. For example, a red apple appears red because it absorbs all other colors of light and reflects only red wavelengths.

3. What is the visible spectrum of light?

The visible spectrum of light is the range of wavelengths that humans can see, which is approximately 400 to 700 nanometers. This includes the colors of the rainbow - red, orange, yellow, green, blue, indigo, and violet.

4. How do different wavelengths of light affect our perception of color?

Our eyes contain specialized cells called cones that are sensitive to different wavelengths of light. The stimulation of these cones by different wavelengths of light creates the perception of color. For example, shorter wavelengths stimulate the blue-sensitive cones, while longer wavelengths stimulate the red-sensitive cones.

5. What is the importance of understanding the wavelengths of different colors of light?

Understanding the wavelengths of different colors of light is crucial in many scientific fields, such as optics, astronomy, and biology. It also plays a significant role in everyday life, as it helps us to see and interpret the world around us and can affect our mood and perception of our surroundings.
