You can make rain in your kitchen. Pour a cup of water into a Pyrex saucepan or Silex coffee maker and heat it slowly over a low heat source. When the water is warm, place on top of it a saucer filled with ice cubes. As the water below is heated, droplets of water form at the bottom of the cold saucer and combine until they are large enough to fall, producing a steady "rainfall" as the water below is gently heated.
How does this resemble and differ from the way natural rain is formed?

Amichelson interferometer operating at a 600 nm wavelength has a 3.02-cm-long glass cell in one arm. to begin, the air is pumped out of the cell and mirror m2 is adjusted to produce a bright spot at the center of the interference pattern. then a valve is opened and air is slowly admitted into the cell. the index of refraction of air at 1.00 atm pressure is 1.00028.how many bright-dark-bright fringe shifts are observed as the cell fills with air?
