![]() ![]() After they meet up again as adults, and he properly falls in love with her, they decide to reaffirm the engagement but are forced into an unusual situation: in order not to shame the Sakuraba family, they must keep their relationship a secret even as they move into a Sakuraba mansion with the help of Aoi's guardian, Miyabi Kagurazaki. Aoi - who had loved him since childhood and dreamed of marrying him - is unable to accept the annulment and tracks down Kaoru to find out why he doesn’t want to marry her. After taking great pains to escort the woman to her destination, he discovers that she is really his childhood friend, Aoi Sakuraba, whom he had promised to marry almost two decades earlier.Įxcept that the engagement was annulled by the Sakuraba clan when Kaoru left the Hanabishi clan, after years of abuse from his grandfather. More oranges and reds reach your eyes in this situation leading to intense sunrises and sunsets.Kaoru Hanabishi, an ordinary college student, runs into a beautiful young woman dressed in an old-fashioned kimono, lost and flustered in the complicated Tokyo subway system. Dust and water particles reflect light just like gas molecules can, therefore having more molecules in the air cause more scattering to occur, causing even less pinks and yellows to reach your eyes. When more molecules are in the atmosphere than normal, say after a major volcanic eruption, the most spectacular sunrises and sunsets can occur. This is why sunrises and sunsets often are composed of pink, red, and orange colors. If the path is long enough, all the blue and violet light gets redirected out of your line of sight, while much of the pink, orange, and red colors continue along the undeviated path between your eyes and the sun. More atmosphere means more molecules to scatter the violet and blue light. So why are sunrises and sunsets red?Īt sunrise and sunset, the sunlight passes through more atmosphere than during the day when the s un is higher in the sky. Space is black because there are very few molecules to scatter light. If you continued upward even more, the sky would slowly turn black as scattering diminishes even more. That is because there are fewer molecules to scatter light at higher elevations, so only the shortest of wavelengths experience the most scattering as you go up further into the atmosphere. If you go to high elevations, the sky directly overhead can be very dark blue or even bluish-violet. The color of the sky near the horizon appears paler or even whitish. ![]() Therefore, less blue light reaches your eyes. Some of it gets scattered away again in other directions. To reach you, the scattered blue light must pass through more air. This process of scattering is known as Rayleigh scattering (named after Lord John Rayleigh, who first described it in the 1870's).Īs you look at the horizon, the sky appears much paler in color. The sky looks blue, not violet, because our eyes are more sensitive to blue light (and the sun also emits more energy as blue light than as violet). While all colors are scattered by air molecules, violet and blue are scattered most. When light bumps into them, some of the light gets reflected, or bounces off the molecule, while the rest of the energy is absorbed by the molecule. Gas molecules are smaller than the wavelength of visible light. Then what happens to the light depends on the wavelength and the size of the thing it hits. As light moves through the atmosphere, it continues to go straight until it bumps into a bit of dust or a gas molecule (like oxygen or nitrogen). ![]() Light travels in a straight line as long as nothing disturbs it. Red has the longest wavelength, and lowest frequency and energy. That means that it also has the highest frequency and energy. Violet has the shortest wavelength in the visible spectrum. The colors have different wavelengths, frequencies, and energies. ![]() These gradually shade into yellow, green, blue, indigo, and violet. At one end of the spectrum are the reds and oranges. The colors blend continuously into one another. Wavelength is the distance between the crests of the light waves as they move through space. White light consists of all the colors we can see, and each of these colors has a different wavelength. Light from the sun or a light bulb may look white, bu t it is actually a combination of colors. Light is a form of electromagnetic radiation (which means it travels in the form of waves possessing electric and magnetic properties). To understand why the sky is blue, we need to understand a little about our atmosphere and light. Why is the sky blue? Understanding the atmosphere and light In the evening, the sunset puts on a brilliant show of reds, oranges, and pinks. On a clear sunny day, the sky above us looks bright blue. ![]()
