A molecular cloud has a temperature of 46 K and an HI cloud has a temperature of 135 K. What are their wavelengths of maximum intensity? What frequency do these correspond to? In what region of the electromagnetic spectrum can the radiation from these clouds be found? Part 1 of 3 We can use Wien's Law to determine the wavelength of maximum intensity in nanometers for the molecular cloud. 2.90 x 106 Amc Amc Amc ^HI AHI = ^HI = We can use Wien's Law again to determine the wavelength of maximum intensity in nanometers for the HI cloud. 2.90 x 106 = = K nm = um K nm um

Stellar evolution

We may see thousands of stars in the dark sky. Our universe consists of billions of stars. Stars may appear tiny to us but they are huge balls of gasses. Sun is a star of average size. Some stars are even a thousand times larger than the sun. The stars do not exist forever they have a certain lifetime. The life span of the sun is about 10 billion years. The star undergoes various changes during its lifetime, this process is called stellar evolution. The structure of the sun-like star is shown below.

Red Shift

It is an astronomical phenomenon. In this phenomenon, increase in wavelength with corresponding decrease in photon energy and frequency of radiation of light. It is the displacement of spectrum of any kind of astronomical object to the longer wavelengths (red) side.
