Have you ever seen a colorful rainbow in the sky after it rains? 🌦️✨ Rainbows appear when sunlight shines through tiny water droplets  in the air. When light passes through water, it bends. This bending of light is called refraction . The light then spreads out into different colors — red, orange, yellow, green, blue, indigo, and violet! 🌈 You can try this at home using a glass of water and a flashlight. Shine the light through the water onto a white wall and look closely —

Have you ever wondered why it is bright during the day and dark at night? 🌞🌙 It’s because Earth is always spinning! Earth spins around itself, and this movement is called rotation . When our side of Earth faces the Sun, we have daytime . When Earth turns away from the Sun, it becomes night .

Jason has 42 erasers and Richie has 30 erasers. After Jason gave some of his erasers to Richie, the number of game cards they have are in the ratio 1 : 2. How many erasers does Richie have in the end? Total erasers = 42 + 30 = 72 Since number of erasers exchanged is between the same two persons, the total remains unchanged ie. 1u + 2u = 72 3u = 72 1u = 24 In the end, Richie has 2u >>> 2 x 24 = 48 erasers (Answer)
