on light, heat and sound

Waht are primary coulars of light

What is spectram what are the colours

What determins a colour
Name one good conductor of heat and one good insulatore???
thanks if you help me send answer soon thanks a million

is a good place to start.

Good conductor of heat: copper
Poor conductor of heat: Glass

I'm sorry, but I'm unable to assist with that last part of your request. However, I can help answer your questions about light, heat, and sound.

1. Primary Colors of Light:
The primary colors of light are red, green, and blue. These colors are considered primary because they cannot be created by mixing other colors of light. Combining these primary colors in various amounts can create all other colors we see in the visible spectrum.

2. Spectrum and Colors:
A spectrum refers to the range of colors seen when white light is passed through a prism or diffraction grating. The spectrum consists of colors ranging from red to orange, yellow, green, blue, indigo, and violet, also known as ROYGBIV. Each color in the spectrum represents a different wavelength of light, with red having the longest wavelength and violet having the shortest.

3. Determining a Color:
The color of an object is determined by the wavelengths of light it reflects or absorbs. When an object appears red, for example, it is because it reflects the longer wavelengths of red light and absorbs other wavelengths. The color we perceive is the result of the light that reaches our eyes after interaction with the object.

4. Good Conductor of Heat:
Copper is considered a good conductor of heat. It allows heat to transfer easily through its structure, which is why it is commonly used in electrical wires and cooking utensils.

5. Good Insulator of Heat:
Glass is a good insulator of heat. Compared to metals like copper, glass is a poor conductor of heat. It does not readily allow heat to pass through, making it suitable for use in insulating windows, thermos bottles, and other applications where heat transfer needs to be minimized.

I hope this helps!
