The following question consists of six sentences of a passage. The first and the sixth sentences are given in the beginning as S1 and S6. The middle four sentences in each have been jumbled up and labelled P, Q, R and S. You are required to find the proper sequence of the four sentences and mark your response accordingly. S1: There have been two schools of thought which deal with the errors of learners. S6: Both views are popular today but the second is gaining ground fast. P: The philosophy of the second school is that errors are natural and they will occur in any learning. Q: So- errors, they say, is a sign of faulty teaching methods. R: The first school maintains that if teaching methods are perfect, errors will never occur. S: They argue that we should concentrate on how to deal with errors, instead of on method of teaching. The correct sequence should be
Refraction from denser to rare medium for a light ray, the value of angle of refraction at the condition of critical angle is
__________ pulps are of especially high opacity. Fillers tend to have high indices of refraction and provide interfaces for light scattering as well. The very high index of refraction of Ti2 allows thin papers to have high opacity as in the case of bible papers.
__________ means that when light travels from a material of less index of refraction to a material of higher index of refraction, the light is bent towards the normal.
Consider the following statements: 1. Precision shows how close the measured value is to the true value of the quantity. 2. Instrumental errors and personal errors are the sources of random errors. 3. Random errors are random with respect to the sign and shape of the quantity. 4. Absolute error is the magnitude of difference between individual value and the true value of the quantity Which of the above statements are correct.
