If you want to get good marks in the upcoming board exam 2019, then practice is the most essential tool. Solving problems based on different conceptual topics helps to reinforce the concepts and retain the knowledge in brain. This way, you will become more efficient in solving the problems asked in the exams.
Jagranjosh brings here the CBSE Class 10 Physics (Science) Practice Paper to revise for the upcoming board exam 2019. This paper consists of all important questions based on important topics of Physics portion of class 10 Science. This CBSE practice paper has been designed after analysing the pattern of questions used in previous years’ board exams. This paper is consisted of different types of questions like short answer type questions, long answer type questions and MCQs, which will help students to familiarise with the different formats of questions asked in board exams. Questions asked in this practice paper will not only help students to get an idea of the important topics to be prepared, but will also help them in understanding the depth with which these topics should be studied.
Few sample questions from the Question Paper are given below:
Q. Name the part of the human eye that helps in changing the focal length of the eye lens.
Q. Name the component of white light which deviates
(i) The least and
(ii) The most while passing through a glass prism.
Q. Why does the clear sky appear blue? How would the sky appear in the absence of earth’s atmosphere?
Q. Draw a ray diagram to show the path of the reflected ray corresponding to an incident ray which is directed parallel to the principal axis of a convex mirror. Mark on it the angle of incidence and the angle of reflection.
Q. Why does the sun seem to rise two minutes before the actual sunrise and set two minutes after the actual sunset? Explain with the help of labelled diagram.
Q. A spherical mirror produces an image of magnification −1 on a screen placed at a distance of 40 cm from the mirror:
(i) Write the type of mirror.
(ii) What is the nature of the image formed?
(iii) How far is the object located from the mirror?
(iv) Draw the ray diagram to show the image formation in this case.
Q. (a) what is meant by fossil fuel?
(b) Which fossil fuel is usually conserved when we save on electricity?
(c) At the present rate of consumption how long will the known reserves of coal and petroleum last?
Q. (a) With the help of ray diagrams, show the formation of image by
(i) a hyperme tropic eye and (ii) correction of hypermetropia by using an appropriate lens.
(b) The near point of a person suffering from hypermetropia is at 50 cm from his eye. what is the power of the lens needed to correct this defect? (near point of normal eye is 25 cm)
(c) What might be the possible reasons for the Hypermetropia?
Q. Hypermetropia is a defect of vision with which a person can see the distant objects clearly but is unable to see the nearby objects distinctly. This defect might be caused due to which of the following reasons:
(i) Eye ball being too short.
(ii) Short focal length of eye lens.
(iii) Eye ball being too long.
(iv) Large focal length of eye lens.
Choose the correct option among the following:
(a) i and ii
(b) ii and iii
(c) i and iv
(d) iii and iv
