The essential conditions for two light waves to be coherent includes that the two waves must be continuous, the two waves should be of the same frequency or wavelength, and they should have a constant or zero phases difference. So, the unnecessary condition for two light waves to be coherent is the statement that the sources should be narrow.

Light undergoes interference, diffraction, and polarization. These phenomena establish that light is a wave motion. Therefore, out of the options, reflection isn’t a suitable phenomenon to establish that light is wave motion.

The ligands given are chlorine (Cl), carbonyl (CO), carbonate (CO₃) and oxalate (C₂O₄). Of these, the one that occurs last in alphabetic order is oxalate, and hence is will be listed at the end of the coordination entity.

The charge of a coordination entity is written without the presence of the counter ion and is indicated outside the square brackets on the right side as a superscript with the number before the sign of charge.

The terms bis, tris, tetrakis are used when the names of the ligand include a numerical prefix. Else, the prefixes used are mono, di, tri, tetra, etc.

ZIFT stands for zygote intra fallopian transfer. This technique is used as a part of test-tube baby program. It involved implantation of zygote or blastomere developed in the test tube into the fallopian tube.

Zygote or an 8-celled blastocyst formed by test tube baby program requires nourishment. Hence it needs to be transferred into the mother for further development. To provide proper implantation, it is transferred into the fallopian tube by the technique called ZIFT or zygote intra fallopian transfer.

IUT stands for intra uterine transfer. An embryo developed in test tube by inducing fertilization requires appropriate conditions for development. IUT is used to provide these conditions inside the womb.

Embryos that have more than 8-cells are ready for implantation. Hence they can be transferred directly to the uterus. This technique is called IUT or intra uterine transfer.

GIFT stands for gamete intra fallopian transfer. It is used to transfer an egg from a donor female to a recipient female.
