FAQs on Why is the Sky Blue? Video Lecture - Physics for Class 10
| 1. Why is the sky blue? |  |
Ans. The sky appears blue because of a phenomenon called Rayleigh scattering. When sunlight passes through the Earth's atmosphere, it interacts with the molecules and tiny particles in the air. The shorter blue wavelengths of light are scattered more than the longer wavelengths, such as red and yellow, which gives the sky its blue color.
| 2. What causes the sky to change colors during sunrise and sunset? | |
Ans. During sunrise and sunset, the path of sunlight through the atmosphere is longer compared to when the sun is directly overhead. This causes the shorter blue and green wavelengths to scatter even more, leaving behind the longer red and orange wavelengths. As a result, the sky appears to change colors, displaying vibrant shades of red, orange, and pink.
| 3. Does the sky always appear blue? | |
Ans. No, the sky does not always appear blue. The color of the sky can vary depending on various factors such as the presence of clouds, dust, pollution, and atmospheric conditions. For example, a cloudy sky may appear gray or white, while a sunset sky can showcase a range of warm colors. However, under normal atmospheric conditions, the sky typically appears blue.
| 4. Is the blue color of the sky the same everywhere on Earth? | |
Ans. The blue color of the sky may not appear exactly the same everywhere on Earth. Factors such as latitude, altitude, and local atmospheric conditions can influence the shade of blue observed. For instance, at higher altitudes, the sky may appear darker or deeper blue due to thinner air and less scattering of light. Similarly, near the equator, the sky might appear paler blue because of higher humidity and greater scattering of light particles.
| 5. Can the color of the sky change during the day? | |
Ans. Yes, the color of the sky can change during the day. As the sun moves across the sky, the angle at which sunlight reaches the Earth's atmosphere changes. This affects the scattering of light and can lead to variations in the color of the sky. For example, at midday when the sun is directly overhead, the sky may appear a deeper blue compared to the slightly paler blue seen in the morning or evening when the sun is lower in the sky.
