Knowing light reflection and refraction class 10 questions and answers will help students of class 10 to bag a decent score in class 10 board exams as well. Go through them will help candidates get a clear idea about how to approach the problems which in turn helps you to solve them in the most efficient way.

So why wait? Read on to find out everything about light reflection and refraction class 10 important questions with answers here. Question 1 Define the principal focus of a concave mirror. Answer: The principal focus of a concave mirror is a point on its principal axis to which all the light rays which are parallel and close to the axis, converge after reflection from the concave mirror. Question 2 The radius of curvature of a spherical mirror is 20 cm. What is its focal length? Question 3 Name a mirror that can give an erect and enlarged image of an object.

Answer: Concave mirror. Question 4 Why do we prefer a convex mirror as a rear-view mirror in vehicles? Answer: We prefer a convex mirror as a rear-view mirror in vehicles because of two reasons :. Question 1 Find the focal length of a convex mirror whose radius of curvature is 32 cm. Question 2 A concave mirror produces three times magnified enlarged real image of an object placed at 10 cm in front of it. Where is the image located? Solution: Because the image is real, so magnification m must be negative.

Thus the image is located at a distance of 30 cm from the mirror on the object side of the mirror. Question 1 A ray of light travelling in air enters obliquely into water. Does the light ray bend towards the normal or away from the normal?

Answer: The light-ray bends towards the normal because the ray of light goes from a rarer medium to a denser medium. Question 2 Light enters from air to glass having refractive index 1. What is the speed of light in the glass? The speed of light in vacuum is 3 x 10 8 ms Question 3 Find out, from Table Also find the medium with lowest optical density.

Answer: From table Question 4 You are given kerosene, turpentine and water. In which of these does the light travel fastest? Use the information given in Table Question 5 The refractive index of diamond is 2. What is the meaning of this statement? Answer: By saying that the refractive index of diamond is 2. Question 1 Define 1 dioptre of power of a lens.

Answer: One dioptre is the power of a lens whose focal length is 1 metre. Question 2 A convex lens forms a real and inverted image of a needle at a distance of 50 cm from it.

Where is the needle placed in front of the convex lens if the image is equal to the size of the object? Also, find the power of the lens. Question 3 Find the power of a concave lens of focal length 2 m. Question 1 Which one of the following materials cannot be used to make a lens? Question 2 The image formed by a concave mirror is observed to be virtual, erect and larger than the object. Where should be the position of the object? Answer: d Between the pole of the mirror and its principal focus.

Question 3 Where should an object be placed in front of a convex lens to get a real image of the size of the object? Answer: b At twice the focal length. Question 4 A spherical mirror and a thin spherical lens have each a focal length of cm. The mirror and the lens are likely to be : a Both concave. Answer: a Both concave. Question 5 No matter how far you stand from mirror, your image appears erect. The mirror is likely to be a plane b concave c convex d either plane or convex. Answer: d Either plane or convex.

Question 6 Which of the following lenses would you prefer to use while reading small letters found in a dictionary? Answer: c A convex lens of focal length 5 cm. Question 7 We wish to obtain an erect image of an object, using a concave mirror of focal length 15 cm. What should be the range of distance of the object from the mirror? What is the nature of the image? Is the image larger or smaller than the object? Draw a ray diagram to show the image formation in this case. Answer: A concave mirror gives an erect image when the object is placed between the focus F and the pole P of the concave mirror, i.

The image thus formed will be virtual, erect and larger than the object. Question 8 Name the type of mirror used in the following situations.

Support your answer with reason. Answer: a Concave mirrors are used as reflectors in headlights of cars. When a bulb is located at the focus of the concave mirror, the light rays after reflection from the mirror travel over a large distance as a parallel beam of high intensity.

Question 9 One-half of a convex lens is covered with a black paper. Will this lens produce a complete image of the object? Verify your answer experimentally. Explain your observations. Answer: A convex lens forms complete image of an object, even if its one half is covered with black paper. It can be explained by considering following two cases. Case I : When the upper half of the lens is covered In this case, a ray of light coming from the object will be refracted by the lower half of the lens.

These rays meet at the other side of the lens to form the image of the given object, as shown in the following figure. Case II: When the lower half of the lens Is covered In this case, a ray of light coming from the object is refracted by the upper half of the lens.

These rays meet at the other side of the lens to form the image of the given object, as shown in the given figure. Question 10 An object 5 cm in length is held 25 cm away from a converging lens of focal length 10 cm. Draw the ray diagram and find the position, size and the nature of the image formed.

The negative value of image height indicates that the image formed is inverted. The position, size, and nature of image are shown alongside in the ray diagram. Question 11 A concave lens of focal length 15 cm forms an image 10 cm from the lens.

How far is the object placed from the lens? Draw the ray diagram. Question 12 An object is placed at a distance of 10 cm from a convex mirror of focal length 15 cm. Find the position and nature of the image.

Thus, image is virtual, erect and diminished. What does this mean? Question 14 An object 5. Find the position of the image, its nature and size. Question 15 An object of size 7. At what distance from the mirror should a screen be placed, so that a sharp focussed image can be obtained?

Find the size and the nature of the image. The image is real, inverted and enlarged in size. Question 16 Find the focal length of a lens of power What type of lens is this? Find the focal length of the lens. Is the prescribed lens diverging or converging? Reflection of light by curved surfaces; Images formed by spherical mirrors, center of curvature, principal axis, principal focus, focal length, mirror formula Derivation not required , magnification.
