Question

why do we see tails of the comet?

Answer 1

Hey friend here is your answer.

As a comet approaches the Sun, it starts to heat up. The ice transforms directly from a solid to a vapor, releasing the dust particles embedded inside. Sunlight and the stream of charged particles flowing from the Sun – the solar wind – sweeps the evaporated material and dust back in a long tail.

Hope it helps you.

Answer 2

it is not tail , its fire . as the comet comes with a high speed , the air in the way gives it friction . from which it gets heated up and burns . it is one of the major functions of our atmosphere.
