Imagine that we stand on any ordinary seaside pier, and watch the waves rolling in and striking against the iron columns of the pier. Large waves pay very little attention to the columns—they divide right and left and re-unite after passing each column, much as a regiment of soldiers would if a tree stood in their way; it is almost as though the columns had not been there. But the short waves and ripples find the columns of the pier a much more formidable obstacle. When the short waves impinge on the columns, they are reflected back and spread as new ripples in all directions. To use the technical term, they are “scattered.” The obstacle provided by the iron columns hardly affects the long waves at all, but scatters the short ripples.
We have been watching a working model of the way in which sunlight struggles through the earth’s atmosphere. Between us on earth and outer space the atmosphere interposes innumerable obstacles in the form of molecules of air, tiny droplets of water, and small particles of dust. They are represented by the columns of the pier.
The waves of the sea represent the sunlight. We know that sunlight is a blend of lights of many colors—as we can prove for ourselves by passing it through a prism, or even through a jug of water, or as Nature demonstrates to us when she passes it through the raindrops of a summer shower and produces a rainbow. We also know that light consists of waves, and that the different colors of light are produced by waves of different lengths, red light by long waves and blue light by short waves. The mixture of waves which constitutes sunlight has to struggle through the obstacles it meets in the atmosphere, just as the mixture of waves at the seaside has to struggle past the columns of the pier. And these obstacles treat the light waves much as the columns of the pier treat the sea-waves. The long waves which constitute red light are hardly affected, but the short waves which constitute blue light are scattered in all directions.
Thus, the different constituents of sunlight are treated in different ways as they struggle through the earth’s atmosphere. A wave of blue light may be scattered by a dust particle, and turned out of its course. After a time a second dust particle again turns it out of its course, and so on, until finally it enters our eyes by a path as zigzag as that of a flash of lightning. Consequently, the blue waves of the sunlight enter our eyes from all directions. And that is why the sky looks blue.
We know from experience that if we look directly at the sun, we will see red light near the sun. This observation is supported by the passage for which one of the following reasons?
  • a)
    It seems reasonable to assume that red light would surround the sun because the sun is basically a large fireball.
  • b)
    It seems reasonable to assume that the other colors of light would either cancel each other or combine to produce red.
  • c)
    It seems reasonable to assume that red light would not be disturbed by the atmospheric particles and would consequently reach us by a relatively direct path from the sun to our eyes.
  • d)
    It is not supported by the passage. The author does not say what color of light should be near the sun, and he provides no reasons that would allow us to assume that the light would be red.
Correct answer is option 'C'. Can you explain this answer?

Understanding the Passage
The passage draws an analogy between waves in the sea and light waves in the atmosphere. It explains how different wavelengths of light behave when encountering obstacles like air molecules and dust particles.
Reasoning Behind Option C
The correct answer is option 'C' because it directly correlates with how the passage describes the behavior of light waves in the atmosphere.
Key Points Supporting Option C
- Different Wavelengths: The passage distinguishes between long waves (red light) and short waves (blue light). It states that long waves are hardly affected by atmospheric particles, allowing them to travel with minimal scattering.
- Direct Path: Since red light (long waves) is not disturbed by atmospheric particles, it can reach our eyes in a relatively direct manner from the sun. This explains why, when looking directly at the sun, we observe red light surrounding it.
- Contrast with Blue Light: In contrast, blue light (short waves) is scattered in all directions due to obstacles in the atmosphere. This scattering contributes to the blue appearance of the sky but does not affect the direct visibility of red light near the sun.
Conclusion
Thus, option 'C' is supported by the passage because it logically explains the observation of red light near the sun, aligning with the passage's discussion on how different light wavelengths interact with atmospheric particles.

This is an extension question. According to the passage, red light would not be significantly deflected and consequently would pass through a relatively direct route from the sun to our eyes. Hence the answer is (C).

Between us on earth and outer space the atmosphere interposes innumerable obstacles in the form of molecules of air, tiny droplets of water, and small particles of dust. They are represented by the columns of the pier.The waves of the sea represent the sunlight. We know that sunlight is a blend of lights of many colors—as we can prove for ourselves by passing it through a prism, or even through a jug of water, or as Nature demonstrates to us when she passes it through the raindrops of a summer shower and produces a rainbow. We also know that light consists of waves, and that the different colors of light are produced by waves of different lengths, red light by long waves and blue light by short waves. The mixture of waves which constitutes sunlight has to struggle through the obstacles it meets in the atmosphere, just as the mixture of waves at the seaside has to struggle past the columns of the pier. And these obstacles treat the light waves much as the columns of the pier treat the sea-waves. The long waves which constitute red light are hardly affected, but the short waves which constitute blue light are scattered in all directions.Thus, the different constituents of sunlight are treated in different ways as they struggle through the earth’s atmosphere. A wave of blue light may be scattered by a dust particle, and turned out of its course. After a time a second dust particle again turns it out of its course, and so on, until finally it enters our eyes by a path as zigzag as that of a flash of lightning. Consequently, the blue waves of the sunlight enter our eyes from all directions. And that is why the sky looks blue.We know from experience that if we look directly at the sun, we will see red light near the sun. This observation is supported by the passage for which one of the following reasons?a)It seems reasonable to assume that red light would surround the sun because the sun is basically a large fireball.b)It seems reasonable to assume that the other colors of light would either cancel each other or combine to produce red.c)It seems reasonable to assume that red light would not be disturbed by the atmospheric particles and would consequently reach us by a relatively direct path from the sun to our eyes.d)It is not supported by the passage. The author does not say what color of light should be near the sun, and he provides no reasons that would allow us to assume that the light would be red.Correct answer is option 'C'.
