1.	Why does a glass slab not disperse light?
Answer» After refraction at two parallel faces of a glass slab, a ray of light emerges in a direction parallel to the direction of incidence of white light. As rays of all colours emerge in the same direction, i.e., the direction of the incidence of white light, there is no dispersion. However, there is lateral displacement.

25.	Prove under the root 7 irrational
Answer» Let us assume that √7\xa0is rational.That is, we can find integers a and b (≠0) such that\xa0a and b are co-prime{tex}\\style{font-family:Arial}{\\begin{array}{l}\\sqrt7=\\frac ab\\\\b\\sqrt7=a\\\\on\\;squaring\\;both\\;sides\\;we\\;get\\\\7b^2=a^2\\end{array}}{/tex}Therefore, a2 is divisible by 7,\xa0it follows that a is also divisible by 7.So, we can write a = 7c for some integer c.Substituting for a, we get 7b2 = 49c2, that is, b\u200b\u200b\u200b\u200b\u200b\u200b2\xa0= 7c2This means that b2 is divisible by 7, and so b is also divisible by 7\xa0Therefore, a and b have at least 7\xa0as a common factor.But this contradicts the fact that a and b are co-prime.This contradiction has arisen because of our incorrect assumption that √7\xa0is rational.So, we conclude that √7\xa0is irrational.

26.	Prove that √7 is irrational
Answer» Let us assume that √7 be rationalThen it must in the form of p/q (q#0) { p and q are co-prime } √7=p/q=> √7 × q=pQuiring on both sides=> 7q2 = p2 ------->(1)p2 is divisible by 7 p is divisible by 7p=7c (c is a positive integer) (squaring on both side)p2=49c2--------> (2) substitute p2 in equipment (1) we get7q2=49c2=>q is divisible by 7Thus q and p have a common factor 7there is a contradictionas our assumption p&q are co-prime but it has a common factorSo that √7 is an irrational.

35.	Prove that .root 3 is irrational number
Answer» Let us assume that √3 is rational.That is, we can find integers a and b (≠0) such that\xa0a and b are co-prime{tex}\\style{font-family:Arial}{\\begin{array}{l}\\sqrt3=\\frac ab\\\\b\\sqrt3=a\\\\on\\;squaring\\;both\\;sides\\;we\\;get\\\\3b^2=a^2\\end{array}}{/tex}Therefore, a2 is divisible by 3,\xa0it follows that a is also divisible by 3.So, we can write a = 3c for some integer c.Substituting for a, we get 3b2 = 9c2, that is, b\u200b\u200b\u200b\u200b\u200b\u200b2\xa0= 3c2This means that b2 is divisible by 3, and so b is also divisible by 3\xa0Therefore, a and b have at least 3 as a common factor.But this contradicts the fact that a and b are co-prime.This contradiction has arisen because of our incorrect assumption that √3 is rational.So, we conclude that √3 is irrational.
