Assertion : Besides chlorophyll a, blue - green and red algae show the presence of phycobiliproteins . Reason : Chlorophyll and phycobiliproteins are integrated into thylakoids.

The substance capable of absorbing blue light from the visible radiation would appear

When an electron jumps from the orbit n=2 to n=4 ,then wavelength of the radiations absorbed will be (R is Ryberg's constant)

[A] : Depletion of ozone layer results in human disease like cancer . [R] : Ozone layer absorbs UV radiations .

when a certain energy is applied to an hydrogen atom, an electron jumps from n =1 to n = 3 state. Find (i) the energy absorbed by the electron. (ii) wavelength of radiation emitted when the electron jump back to its initial state. ( Energy of electron in first orbit = - 13.6 eV , Planck's constant = 6.6225 xx10^(-34) Js, Charge on electron = 1.6 xx10^(-19) C, speed of light in vacuum = 3xx10^(8)ms^(-1)

An electron makes a transition from orbit n = 4 to the orbit n = 2 of a hydrogen atom . The wave number of the emitted radiations (R = Rydberg's constant) will be
