•  The film of the Camera is analog to the retina in the human eye 
  
• ****
• The retina is a thin membrane that covers the internal lower back of the attention.
• Like film in a camera, the retina is the light-touchy surface in which photos from the outdoor international come to a focus.
• ***

• A lake starts freezing because of the cold atmosphere. It will first freeze At the top surface
• ***
• concept:
• when the water freezes to ice, the ice becomes significantly less dense than the water and continues to float on the lake's surface.
• Below 4° Celsius, water becomes less dense as it gets colder, causing water to freeze to float to the top.

• 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
