Coloured?<\/h2>\n\n\n\n<p class=\"has-text-color has-huge-font-size\" style=\"color:#74008b\">Key Notes :<\/p>\n\n\n\n<ol class=\"wp-block-list has-large-font-size\">\n<li><strong>Nature of Sunlight<\/strong>:\n<ul class=\"wp-block-list\">\n<li>Sunlight is composed of a spectrum of colors.<\/li>\n\n\n\n<li>When sunlight passes through a prism or water droplets in the atmosphere, it can be separated into its constituent colors.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Visible Spectrum<\/strong>:\n<ul class=\"wp-block-list\">\n<li>The colors of the visible spectrum include red, orange, yellow, green, blue, indigo, and violet (ROYGBIV).<\/li>\n\n\n\n<li>These colors have different wavelengths, with red having the longest wavelength and violet having the shortest.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>White Light<\/strong>:\n<ul class=\"wp-block-list\">\n<li>When all the colors of the visible spectrum are combined in equal proportions, they form white light.<\/li>\n\n\n\n<li>This is why sunlight appears white to our eyes when it is not separated.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Rainbows<\/strong>:\n<ul class=\"wp-block-list\">\n<li>Rainbows occur when sunlight is refracted (bent) and dispersed (spread out) by water droplets in the atmosphere.<\/li>\n\n\n\n<li>The different colors of a rainbow are a result of this dispersion.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Sunsets and Sunrises<\/strong>:\n<ul class=\"wp-block-list\">\n<li>During sunrise and sunset, sunlight has to pass through more of Earth&#8217;s atmosphere, which scatters shorter wavelengths (blue and green) more than longer wavelengths (red and orange).<\/li>\n\n\n\n<li>This scattering effect is why we often see red and orange hues during these times.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Colors of Objects<\/strong>:\n<ul class=\"wp-block-list\">\n<li>The colors of objects we see depend on the colors of light they absorb and reflect.<\/li>\n\n\n\n<li>A red apple appears red because it absorbs all colors except red, which it reflects.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Artificial Light<\/strong>:\n<ul class=\"wp-block-list\">\n<li>Artificial light sources like incandescent bulbs emit a continuous spectrum of colors and appear white.<\/li>\n\n\n\n<li>Some artificial lights, like fluorescent or LED bulbs, may have a slight color tint due to the materials used in their construction.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Color Perception<\/strong>:\n<ul class=\"wp-block-list\">\n<li>The human eye and brain perceive colors based on the wavelengths of light that reach the retina.<\/li>\n\n\n\n<li>Our perception of color is a complex interplay of light, cones in the eye, and neural processing.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Importance of Sunlight<\/strong>:\n<ul class=\"wp-block-list\">\n<li>Sunlight is essential for life on Earth, as it provides energy for photosynthesis in plants and helps regulate the circadian rhythms in animals, including humans.<\/li>\n\n\n\n<li>It also plays a crucial role in vitamin D synthesis in our bodies.<\/li>\n<\/ul>\n<\/li>\n\n\n\n<li><strong>Conclusion<\/strong>:\n<ul class=\"wp-block-list\">\n<li>Sunlight is, in fact, composed of a variety of colors that can be separated using prisms or raindrops.<\/li>\n\n\n\n<li>However, when all these colors are combined in equal proportions, they appear white to our eyes.<\/li>\n<\/ul>\n<\/li>\n<\/ol>\n\n\n<div class=\"wp-block-image\">\n<figure
