Why the absorption of blue light excites the chlorophyll to higher energy state than absorption of red light?

What are the three types of materials based on the absorption of light?

Maximum absorption of light by chlorophyll-a occurs in which regions of the absorption spectrum?I. Blue,II. Red,III. Green,IV. Yellow.

When chlorophyll absorbs light, it gets excited andrelease

Which of the following processes involves absorption of energy?

Assertion (A): Alkali metal salts with conc.HCl on heating gives characteristic coloured flame. Reason (R): The heat in the flame excited the valence electron to higher energy level and when it drops back, the excess energy emitted as light in the visible region gives colour

Why the first ionization energy of alkaline earth metals higher than that of Ist group.

TRUE or FALSE: The speed of violet light is less than that of red light.

Emission of electrons by the absorption of heat energy is callled……………………emission.
