What are the different colors of light?

Mixing colours

The primary colours of light are red, green and blue. Mixing these colours in different proportions can make all the colours of the light we see. This is how TV and computer screens work. If you look at a screen with a magnifying glass you will be able to see that only these three colours are being used.

Why does the screen turn the color of the light being emitted?

The collisions cause the electrons of the atmospheric atoms to become excited. As the electrons return to their original energy levels, these atoms emit visible light of distinct wavelengths, to create the colors of the display we see. The color of the aurora depends on the wavelength of the light emitted.

What color or colors of light are transmitted by a piece of yellow glass?

What are the colors formed between the CD and flashlight starting from the nearest color from the source of light?

Answer. Answer: The colors that you see on the CD are created by white light reflecting from ridges in the metal. When light reflects off or passes through something with many small ridges or scratches, you often get rainbow colors and interesting patterns.

What color is lowest in energy?

The frequency of the radiation is proportional to its energy and the wavelength of the radiation is inversely proportional to the energy. Red is the lowest energy visible light and violet is the highest. A solid object has color depending on the light it reflects.

What color has lowest frequency?

Red has the longest wavelength, the shortest frequency, and the lowest energy.

What do we call the smaller chunks of Colours?

A byte is a convenient chunk of computer memory, so one byte was devoted to representing the amount of a single primary color. Thus, it takes 3 bytes (24 bits) to represent a single spot of pure color. With 256 values for each primary, we have 256 x 256 x 256 = 16,777,216 colors.

Why are screens black?

Screens that emit light stop producing light when they are turned off. This is true of CRT, OLED, and plasma screens that emit light directly from the pixels, and LCD where the light comes from a backlight. So the screen naturally becomes dark.

Which color of Aurora gives off higher energy light green or red?

Why the different colors? The color of the aurora depends on which gas is being excited by the electrons and on how much energy is being exchanged. Oxygen emits either a greenish-yellow light (the most familiar color of the aurora) or a red light; nitrogen generally gives off a blue light.

Which color of light has the most energy?

Violet has highest energy.

What happens when red light passes through a green filter?

If a green and a red filter are placed together, what colours would you expect to be transmitted? (Answer – no colour will be transmitted, it will appear black. This is because a pure red filter only allows through red light and a pure green filter only allows through green light.

What are the primary colors of light?

See what happens when you mix together the three primary colors of light: red, green and blue.

How do you make a rainbow in your room?


  1. Fill the glass with water.
  2. Put the mirror into the water inside the glass at an angle.
  3. Position the glass so that sunlight shines directly at the mirror. …
  4. Look for a reflection on the wall. …
  5. Adjust the angle of the mirror until you see a rainbow on the wall.

What will happen if you shine a flashlight on a CD?

Tilt the CD back and forth and the colors will shift and change. … Or if it’s a cloudy day, turn out the lights and shine your flashlight at the CD. Hold your piece of white paper so that the light reflecting off the CD shines onto the paper. The reflected light will make fabulous rainbow colors on your paper.
