In a Young's double slits experiment, the source is white light, one of the hole is covered by a red filter and another by a blue filter. In this case:
- A there shall be alternate interference patterns of red and blue
- B there shall be an interference pattern with both red and blue fringes
- C there shall be no interference fringes
- D there shall be the pattern multicolour and blurred
Answer & Solution
Correct Answer
(C) there shall be no interference fringes
Step-by-step Solution
Detailed explanation
Stable interference requires coherent sources with the same frequency. Since red and blue light have different frequencies, they are incoherent and cannot produce a stationary fringe pattern. C) there shall be no interference fringes

In zwitter ionic form, amino acids show amphoteric behaviour as they react both with acids and bases.
Except glycine, all other naturally occurring \(\alpha\) - amino acids are optically active, since the \(\alpha\) -carbon atom is asymmetric. These exist both in 'D' and 'L' forms. Most naturally occurring amino acids have L-configuration. L-Aminoacids are represented by writing the \(-NH_2\) group on left hand side.
