(a) Why are the fruit juices brought from market clearer as compared to those made at home? (b) Name the bioactive molecule produced by Trichoderma polysporum.

State the medicinal value and the bioactive molecules produced Penicillium notatum, Monascus perpureus and Trichoderma polysporum.

The three microbes are listed below. Name the product produced by each one of them and mention their use. (a) Aspergillus niger (b) Trichoderma polysporum (c) Monascus purpureus

When a plane wave front of light, of wavelength lambda , is incident on a narrow slit, an intensity distribution pattern, of the form shown is observed on a screen, suitably kept behind the slit. Name the phenomenon observed. (a) Obtain the conditions for the formation of central maximum and secondary maxima and the minima. (b) Why is there significant fall in intensity of the secondary maxima compared to the central maximum, whereas in double slit experiment all the bright fringes are of the same intensity ? (c) When the width of the slit is made double the original width, how is the size of the central band affected ?
