Why Red Light Is Least Scattered By Fog Or Smoke?


The red light has the largest wavelength among all visible parts of light and so it is scattered the least by the fog of smoke.



Which light is most scattered?

Red color scatters the most since it has the smallest wavelength.


Why Sun looks red at the time of sunset?

This is due to light having. longer wavelengths gets scattered away. shorter wavelengths gets scattered away.


Why is blue more scattered than red?

The type of scattering that occurs is known as Rayleigh scattering named after Lord Rayleigh (John William Strutt) who discovered it. This type of scattering increases as the wavelength of light decreases, so blue light is scattered more than red light by the tiny air molecules in our atmosphere.


Which colour is scattered the most?

The Short Answer:

Gases and particles in Earth's atmosphere scatter sunlight in all directions. Blue light is scattered more than other colors because it travels as shorter, smaller waves. This is why we see a blue sky most of the time.


Why does sun appear white in noon?

Answer: (a) light is least scattered

Because the sun is overhead at noon, there is the least amount of scattering, therefore it appears white. When it is overhead, there is less air to travel through, and dust and other particles scatter, which will be reduced if the distance travelled in the air is reduced.


Why red light is least scattered by fog or smoke?

The red light has the largest wavelength among all visible parts of light and so it is scattered the least by the fog of smoke.


Why is red light scattered more?

Red light has double the wavelength of blue light, and is therefore scattered 16 times less. Rayleigh discovered that scattering is strongest in the direction light travels, becoming half at right angles to the incident direction of light.


Is blue light stronger than red light?

Blue light has shorter waves, with wavelengths between about 450 and 495 nanometers. Red light has longer waves, with wavelengths around 620 to 750 nm. Blue light has a higher frequency and carries more energy than red light.


Why is light scattered?

When sunlight enters the atmosphere of the earth, the atoms and molecules of different gasses present in the air absorb the light. Then these atoms re-emit light in all directions. This process is known as Scattering of light.


Why does red have the lowest frequency?

When it comes to visible light, the highest frequency color, which is violet, also has the most energy. The lowest frequency of visible light, which is red, has the least energy.


Why blue light is scattered but red light is not?

Thus, as sunlight of all colors passes through air, the blue part causes charged particles to oscillate faster than does the red part. The faster the oscillation, the more scattered light is produced, so blue is scattered more strongly than red.


What is the uncertainty in its velocity?

The uncertainty principle is alternatively expressed in terms of a particle's momentum and position. The momentum of a particle is equal to the product of its mass times its velocity. Thus, the product of the uncertainties in the momentum and the position of a particle equals h/(4π) or more.


How do you calculate the uncertainty of an electron?

Mass of an electron = m = 9.1 x 10-31 kg. Uncertainty in position = ∆x = ? = 1 x 10-10 m. Uncertainty in position = 1 x 10-10 m.


Why is Antarctica considered a global commons?

Antarctica is one of four internationally recognised global commons. Not only has nation state sovereignty remained unrecognised on the continent but it also run by the principles of peace, science and environmental protection – principles that are key to ga global commons.


Is Upcet admit card 2021?

What is unique about the boron family?

The elements present in the group 13 of the modern periodic table are known as Boron family (includes B, Al, Ga, In, Tl, Uut). These elements have 3 electrons in their outermost shell. Only one member of this family i.e. boron is typically a non-metal.


What do you know about the anomalous behaviour of boron in terms of a Covalency and B nature of oxides?

Solution : The anomalous behaviours of boron are as follows : <br> (a) Boron is a harder element than the other elements of its group . (b) It has high melting and boiling points compared to other members of the group . (c ) It forms only covalent and ionic compounds .


What are uses of boron?

Applications for Boron

  • Glass (e.g., thermally stable borosilicate glass)
  • Ceramics (e.g., tile glazes)
  • Agriculture (e.g., boric acid in liquid fertilizers).
  • Detergents (e.g., sodium perborate in laundry detergent)
  • Bleaches (e.g., household and industrial stain removers)
