Quick Answer: Which Colour Is Least Scattered By Fog?

Which component of white light is least scattered by fog or smoke?

Red colourWhich of the following statements is correct regarding the propagation of light of different colours of white light in air.

Explanation: Speed of light is a constant value regardless of its color.

Explanation: Red colour is scattered the least by smoke or fog due to its largest wavelength..

Which Colour of white light is scattered the least and why?

red colourThe red colour of the white light is scattered the least because of its longer wavelength while the violet coloured is scattered the most.

Which Colour of light is scattered the least?

Air molecules scatter light in this way because they are very small (much smaller than the wavelength of visible light). Violet has the shortest wavelength and is scattered the most. However there isn’t as much violet in sunlight as there is blue and green.

Which component of white light is scattered the most by the fog or smoke and why?

Answer. violet colout of white light is most scattered by the fog or smoke because of its its smaller wavelengths..

Which of the following Colour is least scattered?

Red lightRed light has longest wavelength, and hence it is least scattered. Violet light has the shortest wavelength, and hence it is the most scattered light.

Which of the following Colours is least scattered by fog dust of snow?

Red colorRed color scatters the least by fog, dust or smoke as they have largest wavelength hence they are used for signal lights so that they can be visible in dense fog or smoke as well.

Which Colour has maximum scattering?

Physical derivations show that for Rayleigh scattering, the higher frequency colors such as blue and violet are scattered much more strongly than low frequency colors such as red and orange. Mathematically, the intensity of scattered light is proportional to f 4, where f is the frequency of the light.

Which color is most scattered?

Blue lightBlue light is scattered in all directions by the tiny molecules of air in Earth’s atmosphere. Blue 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.

Which light is scattered most?

Rayleigh Scatter Light at shorter wavelengths (like blue and violet visible light) are scattered by small particles that include NO2 and O2. Since blue light is at the short wavelength end of the visible spectrum, it is more strongly scattered in the atmosphere than longer wavelength red light.

Which light is easily scattered?

Blue light has shorter wavelength, so it is scattered more easily. Red light has longer wavelength, so it is not scattered much. The blue coloured light present in white sunlight is scattered much more easily than the red light.

Why is the sky blue quantum mechanics?

Cause of the blue color of the sky The strong wavelength dependence of the scattering (~λ−4) means that shorter (blue) wavelengths are scattered more strongly than longer (red) wavelengths. … It is this scattered light that gives the surrounding sky its brightness and its color.
