A rainbow is an optical and meteorological phenomenon that causes a spectrum of light to appear in the sky when the Sun shines onto droplets of moisture in the Earth's atmosphere. They take the form of a multicoloured arc, with red on the outer layer and violet (or purple) in the inner section. The rainbow consists of seven colours wich are red, orange, yellow, green, blue, indigo and violet. Rainbows can be caused by other forms of water apart from rain including mist, dew and spray.

FranA rainbow forms when sunlight is refracted, or bent, at different angles as it passes through water droplets in the atmosphere. This causes the sunlight to separate into its individual colors, creating the arc of colors we see in the sky. The specific angle of refraction and reflection within the water droplets results in the circular shape of the rainbow.

Why is a bow an elastic form of energy?
A bow is considered an elastic form of energy because when it is drawn back, it stores potential energy in the form of elastic deformation of the bow and the bowstring. When the bowstring is released, this potential energy is converted into kinetic energy in the arrow, which then propels the arrow forward.
How do clouds let go of rain?
Clouds release rain through a process called precipitation. When air cools and reaches its dew point, water droplets within the cloud combine to form larger droplets, eventually becoming heavy enough to fall as rain. This process can also occur with snow or hail, depending on the temperature.
What substance is placed on a bow to increase friction?
Rosin, a solid form of resin, is commonly used on bows for string instruments to increase friction between the bow and the strings. This helps create a clearer and more consistent sound by allowing the bow to grip the strings better as it is drawn across them.
Raindrops falling on frozen ground form this?
Ice pellets or sleet.
Does rain help a tornado?
No, rain does not help a tornado form. Tornadoes are formed by severe thunderstorms with specific atmospheric conditions, such as wind shear and instability. Rain can occur before, during, or after a tornado, but it is not a contributing factor to the formation of a tornado.
