Do some wavelengths of light cause more newspaper yellowing than others?
the major cause of newspaper yellowing is leftover processing acids in the pulp used to make the paper, not light.
Which type of light penetrates the least in water?
Red
How are different wavelengths of visible light transmitted by water?
When visible light enters water, shorter wavelengths (blue and violet) are absorbed and scattered more by water molecules than longer wavelengths (red and orange). This is why water appears blue as it absorbs the shorter blue wavelengths and reflects them back. Hence, longer wavelengths penetrate deeper into water, making red light the most visible at greater depths.
Does the sun appears reddish as it sets because the sun emits more radiation at longer wavelengths at sunset?
Yes, at sunset the sun's light has to pass through more of the Earth's atmosphere, which scatters shorter wavelengths of light, leaving mostly longer, reddish wavelengths to reach our eyes. This is why the sun appears reddish as it sets.
What has more energy a visible light or infrared light?
Visible light. It has a higher frequency so more energy.
What affects light with short wavelengths more than light with long wavelengths?
Scattering of light
What bends more light waves with short wavelengths or light waves with long wavelenths?
Light waves with shorter wavelengths bend more compared to light waves with longer wavelengths when passing through a medium due to the phenomenon of dispersion. This is why we see rainbows, where shorter wavelengths (violet/blue) are bent more than longer wavelengths (red) when passing through water droplets.
Why are Chlorophyll b and the carotenoids important as receptors of light energy?
These pigments are able to absorb more wavelengths of light (and thus more energy) than chlorophyllaalone can absorb. As part of light-harvesting complexes in photosystems, they broaden the range of light that can be used in the light reactions.
Short wavelengths are what type of light?
Short wavelengths are typically associated with high-energy light, such as gamma rays, X-rays, and ultraviolet light. These types of light have more frequent oscillations and carry more energy per photon compared to longer wavelengths.
Is red or violet light diffracted most?
Violet light is diffracted more than red light because shorter wavelengths are diffracted more than longer wavelengths.
Why does this make the color appear blue?
The color appears blue due to the way light interacts with materials and how our eyes perceive it. When light strikes an object, certain wavelengths are absorbed while others are reflected. If an object reflects primarily blue wavelengths and absorbs others, it will appear blue to our eyes. Additionally, phenomena like Rayleigh scattering in the atmosphere can cause the sky to appear blue, as shorter blue wavelengths scatter more than longer wavelengths.
Do some wavelengths of light cause more newspaper yellowing than others?
the major cause of newspaper yellowing is leftover processing acids in the pulp used to make the paper, not light.
Can the color of an object depend on the light it reflects?
Yes, the color of an object can depend on the light it reflects. Objects appear to have color because they reflect certain wavelengths of light while absorbing others. The specific wavelengths that are reflected determine the color we perceive.
What is the relationship between the light bulb wavelength and its energy efficiency?
The relationship between the wavelength of light emitted by a light bulb and its energy efficiency is that shorter wavelengths, such as blue light, are more energy efficient than longer wavelengths, such as red light. This is because shorter wavelengths carry more energy per photon, allowing for more efficient conversion of electricity into light.
Why are objects coloured?
It is because they reflect certain wavelengths (colors) of light more readily than others. White light contains all wavelengths of light. You can see this by passing the light through a prism or by observing a rainbow. Now, if you have an object such as an orange and shine white light on it. The red and yellow will be reflected and the other colors will be absorbed. Thus, we see an orange object. Now, if you shined pure blue light on the orange it would look black, because there would be no red or yellow to reflect.
How do you know that objects reflect more than 1 color?
Objects reflect multiple colors because they absorb certain wavelengths of light while reflecting others. The reflected light that reaches our eyes is a combination of these different wavelengths, which our brain processes as different colors. This phenomenon is known as visible light absorption and reflection.
What wavelengths will be bend more once it passes through a prism?
Shorter wavelengths (like blue light) will bend more than longer wavelengths (like red light) when passing through a prism due to the phenomenon of dispersion. This is because shorter wavelengths are more strongly refracted by the prism material, causing them to separate more distinctly from each other.
