CBSE I NCERT Chapter -Light _Refraction and Refraction solved Questions

VERY SHORT QUESTIONS CARRYING 1 MARK EACH.
1. Out of convex mirror and concave mirror, whose focus is situated behind the mirror?
Ans: The focus of convex mirror is situated behind it.
2. For what position of an object, a concave mirror forms an enlarged virtual image?
Ans: Object between pole (P) and focus (F) of the concave mirror.
3. If the focal length of a concave mirror is 25cm. What is its radius of curvature?
Ans: Focal length = Radius of curvature / 2
25 = R / 2  => R = 50cm.
4. A ray of light falls on a mirror normally. What are the values of angle of incidence andthe angle of reflection?
Ans: Both angle of incidence and the angle of reflection are zero.
5. What is the focal length of a plane mirror?
Ans: Infinite.
6. Which spherical mirror is called a divergent mirror?
Ans: A convex mirror is called a divergent mirror.
7. What is the angle of incidence, when a ray of light falls on the spherical mirror from itscentre of curvature?
Ans: The angle of incidence is zero, when a ray of light falls on the spherical mirror from its centre of curvature.
8. Name the type of mirror that always forms a virtual image for a real object?
Ans: Convex Mirror.
9. State the relation between radius of curvature and focal length of spherical mirrors.
Ans: Radius of curvature = 2 X focal length.
R = 2f.
10. Which of the two is a diverging lens? Convex lens (or) Concave lens.
Ans: Concave lens.
11. If an object is placed at a distance of 10cm in front of a plane mirror, how far would it be from its image?
Ans: The object would be at a distance of 20cm from its image.
12. Name the physical quantity which remains the same when light goes from one medium to another?Ans: Frequency of light.
13. Define power of a lens.
Ans: The reciprocal of the focal length of the lens is called power of a lens. P = 1/f
14. Calculate the power of a convex lens of focal length 25cm?
Ans: Focal length f = 25cm.
Power = 1/.25 = 100/25 = +4D.
15. Name the phenomenon responsible for the following affect.
When we sit in front of a plane mirror and write with our right hand, it appears in the mirror that we are writing with the left hand.
Ans: Lateral Inversion.
16. Define Refractive Index:
Ans: It is the ratio of speed of light in vacuum to the speed of light in medium is called Refractive index.
17. Why is the convex lens also known as a converging lens?
Ans: A convex lens is also known as a converging lens because it converges a parallel beam of light raying passing through it.
18. Give the ratio of velocities of two light waves travelling is vacuum and having wave lengths 4000A0 and 8000A0.
Ans: In Vacuum, light of all the wave lengths travel with the same velocity i.e. 3 X 108 m/sec.
19. For what angle of incidence, the lateral shift produced by parallel sided glass plate is zero?
Ans: For i = 0.
20. What are the factors on which the lateral shift depends?
Ans: Thickness of the refracting medium, angle of incidence and its refractive index.
21. What is the power of a plane glass plate?
Ans: Zero.
22. An object is placed at the focus of a concave lens. Where will its image be formed?
Ans: The rays will appear to come from infinity. Therefore, a virtual image will be formed at infinity.
23. What is the unit of power of a lens?
Ans: Dioptre.

National Level Science Talent Search Examination 2011


National Level Science Talent Search Examination
NSTSE is a diagnostic test which actually helps students improve.
Unlike regular tests which try only to find out how much a child knows (or has memorized), NSTSE measures how well a student has understood concepts and gives detailed feedback on the same, to help them improve.

Thus NSTSE helps each student know whether he/she has actually understood a concept early on so that immediate action can be taken. Often students have conceptual gaps which increase as they progress and when they reach the higher classes, they develop a "phobia" for the subject.

School tests - including board exams - tend to be superficial, testing what children have memorised. But the important skills like the ability to think independently and reason logically - critical in today's world - are often not emphasised in school tests.
The focus on fundamentals is so important that when the child finishes studies he/she will have to face the competitive world armed with these fundamentals. Even while opting for higher studies, the student has to go through a complete scan of what he/she knows and how much. Exams like IIT-JEE, AIEEE, AFMC, AIIMS, GRE, GMAT, CAT etc., are so designed to test the fundamental strength of student. Hence the need of the hour is building the fundamentals base as strong as possible.
This exactly is the philosophy behind the Unified Council's NSTSE.

NSTSE is unlike other tests in many different ways. It

X CBSE | NCERT E- Notes For Ch - Periodic Classification of Elements of Elements

Classification of elements: the arrangement of elements in such a manner that elements with similar properties are grouped together while elements with dissimilar properties are separated.

EARLY ATTEMPTS OF CLASSIFICATION OF ELEMENTS
1. Lavoisier’s classification of elements: In 1789, Lavoisier first attempted to classify the elements into two divisions namely Metals and Non-metals. However this classification was not satisfactory as there were many exceptions in each category.
2. Dobereiner’s classification of elements: In 1817, Johann Wolfgang Dobereiner grouped three elements into what he termed triads.
In each case, the middle element has an atomic mass almost equal to the average atomic masses of the other two elements in the triad.
For example, elements like lithium, sodium and potassium have atomic masses 7, 23 and 39 respectively. They are grouped together into a triad as,
Li (7) Na (23) K (39)
Here the atomic mass of sodium is the average of atomic masses of lithium and potassium.
Limitation of Dobereiner’s law
Only three triads were identified from the element known at that time. Hence, this classification was not useful.

Problem related to factorization,ratiolization

CBSE MATH STUDY: Problem related to factorization,ratiolization:Problem-1 If the values of a – b and ab are 6 and 40 respectively, find the values of a2 + b2 and (a + b)2.
Solution: a2 + b2 = (a – b)2 + 2ab = 62 + 2(40) = 36 + 80 = 116
(a + b)2 = (a – b)2 + 4ab = 62 + 4(40)= 36 + 160 = 196
Problem-2. If (x + p)(x + q) = x2 – 5x – 300, find the value of p2 + q2.
Solution:
By product formula, we have (x + p) (x + q) = x2 + (p + q)x + pq.
So, by comparison, we get p + q = –5, pq = –300.
Now, we have p2 + q2 = (p + q)2 – 2 pq = (–5)2 –2(–300) = 25 + 600 = 625.
Problem-3. If (x + a)(x + b)(x + c) ≡ x3 – 6x2 + 11x – 6, find the value of a2 + b2+ c2.
Solution: From the product formula, we have
(x+a)(x+b)(x+c) = x3 + (a + b + c)x2 + (ab + bc + ca)x + abc.
Comparing, we get a + b + c = –6, ab + bc + ca = 11, abc = –6.
a2 + b2 + c2 = (a + b + c)2 –2 (ab + bc + ca) = (– 6)2 – 2(11) = 36 – 22 = 14.
Problem-4 If a+b=2 and a2+b2=8,find a3+b3 and a4+b4.
