At certain altitude, the temperature of air decrease, The air becomes saturated and water vapour molecules starts condensing.
As the altitude of air increase, the atmospheric pressure decrease due to which the temperature of the air decrease. The water molecules in the atmosphere start condensing, which saturate the air (that is air can no hold water molecules), due to which the water vapour molecules starts condensing and falls on the earth in the form of rain.
The basic relationship between frequency and wavelength for light (which is an electromagnetic wave) is
where c is the speed of light, f the frequency and
the wavelength of the wave.
Using
and
, we can find the value of the frequency:
Explanation:
If you want to get speed, u have to divided distance over time
The lowest speed will lose
A black hole is a cosmological object that is created when a massive star comes to the end of its life and collapses under its own gravity. Black holes have massive gravitational fields that even light cannot escape beyond a certain distance. Before being engulfed, matter that is pulled into a black hole should become very hot and emit electromagnetic radiation.
