    *Question:* Light reflected off spherical objects always concentrates at a point, it doesn't evenly illuminate the whole spehere. Why dont the planets (or moon) ever adhere to this?
    *Example:*
    🪀🟣 See the top of there emojis. The artist added white highlights to show they are spherical.
    Look around your room for spherical or cylindrical (like a soda can) and you'll see the same concentration of light .

    But if there apparent size looks same as stars then they should flicker too. Only if they appear bigger even to the naked eyes then its possible that the efect of flickering of all points cancels out

    I've seen the video: Why is the sky blue, but can you clarify my doubt.
    Why do astronauts looking from space don't see the blue colour of the sky.
    Blue light does get scattered in the atmosphere, so, ideally everyone should see the sky to be in blue in colour no matter where they look from (unless it is night because there is no sunlight).
    Can you please answer it as quickly as possible. (It is a question in CBSE class 10 too)

    • @palak6981
      @palak6981 5 років тому

      The sky for an astronaut is not the same as the sky for a person on earth. His sky is overhead, which is just empty space.

    • @ritz2156
      @ritz2156 5 років тому

      Pranav Koka there is no atmosphere in the sky to scatter the light if there is no atmosphere that means there is no nitrogen or any form of air molecules is present so there is no scattering of light
