Hello student
In this video we are talking about laws that are governing photochemistry and spectroscopy. Here are some questions from the topic if you have any other question then please comment me and subscribe my channel.

1). What is the first law of photochemistry ?
A). The Grotthuss–Draper law (also called the principle of photochemical activation) states that only that light which is absorbed by a system can bring about a photochemical change.

Q). State Stark Einstein law.
Or
Give the second law of photochemistry? .
A).Stark–Einstein law
It is also known as the photochemical equivalence law or photoequivalence law. In essence it says that every photon that is absorbed will cause a (primary) chemical or physical reaction. The photon is a quantum of radiation, or one unit of radiation.

Q). Explain Lambert beer law?
A). The Beer-Lambert law is a linear relationship between the absorbance and the concentration, molar absorption coefficient and optical coefficient of a solution: The molar absorption coefficient is a sample dependent property and is a measure of how strong an absorber the sample is at a particular wavelength of light.
