When a solution is red, does it absorb or transmit red light?
If it absorbed red would you see it? You see what is transmitted.
It absorbs and transmits light
are they right
When a solution appears red, it means that it absorbs other colors of light and reflects or transmits red light. Absorption occurs when a material absorbs certain wavelengths of light and reflects or transmits the remaining wavelengths. So, when a solution appears red, it means it is absorbing all colors of light except red, which is being transmitted or reflected. Therefore, you would see the red light that is transmitted or reflected by the solution.
When a solution appears red, it means that it absorbs light of other colors but transmits or reflects red light. This is because the red color of visible light corresponds to a specific wavelength range, and when light of that wavelength range interacts with the solution, it is not absorbed but allowed to pass through or be reflected.
To understand whether a solution absorbs or transmits red light, you can experiment with colored filters and a light source. Here's a step-by-step explanation of how you can determine this:
1. Obtain a light source, such as a flashlight or a lamp, that emits white light. White light contains all colors of visible light.
2. Take a sample of the solution you want to examine. Ensure that it is in a transparent container.
3. Obtain three different filters: a red filter, a blue filter, and a green filter. These filters are usually sheets of colored acetate or glass.
4. Place the red filter in front of the light source and shine the light through the solution. Observe the color of the light that passes through the solution.
- If the solution appears red when viewed through the red filter, it means that the solution is transmitting red light and not absorbing it.
- If the solution appears colorless or if the color changes significantly when viewed through the red filter, it means that the solution absorbs red light.
Remember that you see the color that is transmitted or reflected by the solution, not the color it absorbs. So, when a solution appears red, it means that it is transmitting red light, enabling you to perceive its red color.
