Colour is decided by the frequency of the electromagnetic wave ie light. There are cones and rods in our retina. The cones are sensitive to the frequency of the electromagnetic radiations falling on it. So colour is sensed by us. If there be any problem with those cones then colours cannot be differentiated. Such persons are called as colour blind people. Any way there is a limitation of sensing the frequencies. So right from red (lower freq) to violet (higher) are visible to our vision. Beyond these limits we cannot see.

ProfessorLight colors are perceived by the human eye through specialized cells called cones in the retina. These cones are sensitive to red, green, and blue light, and the brain processes the signals from these cones to create the perception of different colors. The combination of these signals allows us to see a full spectrum of colors.

Which primary colors are used for mixing new colors using lights?
The primary colors used for mixing new colors using lights are red, green, and blue. Mixing these primary colors in different combinations can produce a wide range of colors in the visible light spectrum.
Can a glass slab bend different coloured lights by different amounts?
Yes, a glass slab can bend different colored lights by different amounts due to the phenomenon of dispersion, where light of different colors is refracted by different angles, resulting in a separation of colors. This is why we see rainbows when light passes through raindrops or a prism.
What is the spectrum of fluorescent lights and how does it affect the quality of light emitted?
Fluorescent lights emit a spectrum of light that includes a range of colors. The quality of light emitted by fluorescent lights can be affected by the specific mix of colors in the spectrum. This can impact how natural or artificial the light appears, as well as how well it renders colors in a space.
What is the scientific explanation for how the northern lights are made?
The northern lights, also known as auroras, are created when charged particles from the sun collide with gases in Earth's atmosphere. These collisions produce light, creating the beautiful colors and patterns we see in the sky.
When you mix colored lights you blank colors until you get white?
When you mix colored lights, you add colors until you get white. This is known as additive color mixing. By combining red, green, and blue light in different intensities, you can create white light because the three colors together cover the entire visible spectrum.
