In this section, we will describe different types of software testing. Various types of software testing are performed to achieve different objectives when testing a software application. You can also read about different Software Testing Techniques which can be associated with various types of software testing.

H-alpha (HÎ±) is a specific deep-red visible spectral line in the Balmer series created by hydrogen with a wavelength of 656.28 nm, which occurs when a hydrogen electron falls from its third to second lowest energy level.herefore, the H-alpha line occurs where hydrogen is being ionized. The H-alpha line saturates (self-absorbs) relatively easily because hydrogen is the primary component of nebulae, so while it can indicate the shape and extent of the cloud, it cannot be used to accurately determine the cloud's mass.
