D. It is cooler at sunrise and at sunset
Check answer and explanation
Answer: Of Scattering of light due to dust particles and air molecules.
Explanation the sun appears red at sunrise and sunset while it appears white at noon because Of the Scattering of light due to dust particles and air molecules. *** concept: It is due to the scattering of light. At noon, the su n is at the nearest point to earth. Hence all the colors get scattered almost equally and this you see white light. But during sunrise and sunset, the sun is at the longest position. Here blue light gets scattered off and due to the larger wavelength of red light, it can travel a longer distance and hence reach our eyes. This we see the sun's red

B. To Study position of Stars
C. To Study movement of Stars
D. To study radio waves of Stars
Check answer and explanation
Answer: To study chemical composition of Stars
Explanation In space exploration , a spectroscope is typically used to analyze the light coming from stars, planets, and other celestial objects to determine their chemical composition. This helps scientists understand the formation and evolution of stars, planets, and galaxies.
Explanation Jupiter has the shortest day of any planet in our solar system It completes one rotation in approximately 9 hours and 56 minutes . It is also the fastest-spinning planet in the solar system.
Explanation The telescope is undoubtedly the most important investigative tool in astronomy. A celestial body that revolves around a planet is known as a natural satellite .
Explanation The speed of light is much faster than the speed of sound in air. Light travels 186 thousand miles in 1 second. While sound takes almost 5 seconds to travel 1 mile.
