S2.Ans. (c); Diffraction is defined as the bending of light around the corners of an obstacle or aperture into the region of geometrical shadow of the obstacle.
S3.Ans.(d); Mirage formation is a result of the refraction and the total internal reflection of light in the air.
S4. Ans .(c); Fortran is not used for drawing pictures and carrying out mathematical computations. Fortran is a general-purpose, imperative programming language that is especially suited to numeric computation and scientific computing.
S5. Ans.(d); Hydrogen bonds are classified as weak bonds because they are easily and rapidly formed and broken under normal biological conditions.
S6. Ans .(d); When an acid and a base are placed together, they react to neutralize the acid and base properties, producing a salt. The H(+) cation of the acid combines with the OH(-) anion of the base to form water.
S7.Ans. (a); BISHNOI MOVEMENT was started in 1700s in Khejarli, Marwar region, Rajasthan state.
