Comets leave long beautiful tails when they come close to the sun. But when it approaches the sun, the heat evaporates the comet's gases, causing it to emit dust and microparticles (electrons and ions). ... These materials form a tail whose flow is affected by the sun's The radiation pressure again can be seen as the transfer of each photon's momentum to the opaque surface, plus the momentum due to a (possible) recoil photon for a (partially) reflecting surface.
Why do comets have tails quizlet?
Q: Why do comets have a long tail? A: A comet is made of ice and as it gets closer to the sun, the ice is vaporized and gets turned into a gas and creates a tail.
Why do comets go tail first?
But as it comes closer to the Sun, the warming of its surface causes its materials to melt and vapourise producing the comet's characteristic tail. ... As can be seen from the diagram, the tail of the comet always point away from the Sun, so after a comet has passed the Sun it actually travels tail first.
