What is correct about the following satement (a) Portion of spectrum between 500-800 nm is PAR (b) Mg, Ca, Cl have prominent role in photolysis of water In cyclic photophosphorylation, O_(2) and NADPH are not produced

Which of the following statement is / are incorrect ? (i) Green light falling in the range of wavelength 500 0 -580 nm is least effective for photosynthesis. (ii) In non - cyclic photophosphorylation, the electron expelled from the reaction centre is not cycled back , though its loos is compensated by electrons from the photolysis of water . (iii) Chl a , Chl b , carotenoids , and xanthophylls are insoluble in organic solvents. (iv) 400-700 nm light is used in photosynthesis also known as PAR. (v) Red light is the most effective for photosynthesis.

(i) A powdered substance (A) on treatment with fusion mixture gives a green coloured compound (B). (ii) The solution of (B) in boiling water on acidification with dilute H_(2)SO_(4) gives a pink coloured compound (C ). (iii) The aqueous solution of (A) on treatment with NaOH and Br_(2)- water gives a compound (D). (iv) A solution of (D) in conc. HNO_(3) on treatment with lead peroxide at boiling temperature produced a compound (E) which was of the same colour at that of (C ) .

Read the following text and answer the following questions on the basis of the same: Laser: Electromagnetic radiation is a natural phenomenon found in almost all areas of daily life, from radio waves to sunlight to X-rays. Laser radiation - like all light - is also a form of electromagnetic radiation Electromagnetic radiation that has a wavelength between 380 nm and 780 nm is visible to the human eye and is commonly referred to as light. At wavelengths longer than 780 nm, optical radiation is termed infrared (IR) and is invisible to the eye. At wavelengths shorter than 380 nm, optical radiation is termed ultraviolet (UV) and is also invisible to the eye. The term "laser light" refers to a much broader range of the electromagnetic spectrum that just the visible spectrum, anything between 150 nm up to 11000 nm (i.e. from the UV up to the far IR). The term laser is an acronym which stands for "light amplification by stimulated emission of radiation". Einstein explained the stimulated emission. In an atom, electron may move to higher energy level by absorbing a photon. When the electron comes back to the lower energy level it releases the same photon. This is called spontaneous emission. This may also so happen that the excited electron absorbs another photon , releases two photons and returns to the lower energy state. This is known as stimulated emission. Laser emission is therefore a light emission whose energy is used, in lithotripsy, for targeting and ablating the stone inside human body organ. Apart from medical usage, laser is used for optical disk drive, printer, barcode reader etc. What is the full form of LASER?
