    Guys relax! actually sir got some misconception , it will be warm layer trapped between cool layers , also warm layer ki density is less than cold layer so when light move from cool to warm it will get internally reflected

    @mylab188 3 года назад +3

    Sir, please guide me that if there is a decrease in temperature with height then it is considered as standard atmosphere.
    Then inverse should be opposite i.e here temperature should increase with height.
    And finally we get a layer of warm air being trapped between layers of cool air.
    The above is my view point, which differs from yours. Please help.
