What are the essential conditions for formation of shadows? When a ray of light falls on a surface like glass which has shiny and glossy properties from where light gets reflected. Give four examples of translucent object. the sunlight falls normally or orthogonally on the object (this is possible only in the region between the Tropic of Capricorn and Tropic of Cancer), then the angle of elevation becomes equal to 90, and cot() = 0. RD Sharma Solutions , RS Aggarwal Solutions and NCERT Solutions. The formation of shadows by celestial bodies on one another is called an eclipse. It is a form of energy which makes objects visible as we cannot see objects in darkness. (c) erect but laterally inverted We can see only in the presence of light. Define opaque objects with example. Question 26. The unlighted area is called the shadow. WebAerial photograph interpretation is a method of extrapolating geological details of the ground surface from aerial images. Mirrors show regular and complete reflection. WebA shadow is formed when an opaque object blocks the path of light because light travels in straight lines.Light cannot bend around the object so it forms a shadow. A shadow is a dark shape made when light is stopped or blocked by an object or a person. (b) Why do you think that some people believe that these eclipses will have some bad effect on them? Images have colour, unlike shadows. Answer: We may say that clouds behave as translucent object. A rain shadow forms when moist winds head towards a set of mountains and get forced upwards by them. Light is emitted from a source such as the Sun. For this, take a cylindrical tube; which can be easily bent. (b) reflected ray Practice MCQ Questions for Class 6 Science with Answers on a daily basis and score well in exams. What is this called? Black thick paper is translucent. Question 9. Reflection occurs mainly on the mirror surface as incident light gets reflected when it falls on a clear surface and due to reflection the image formed is always erect. It is formed when light hits the opaque object which does not let the light pass through. Or, it can even mislead us about the shape of different objects. WebA shadow is formed when there is a source of light. Non luminous: Air, water, a piece of rock, a sheet of aluminium, a mirror, a wooden board, a sheet of polythene, a CD, smoke, a sheet of plane glass, fog, an umbrella, a wall, a sheet of carbon paper, a sheet of cardboard, a sheet of cellophane, a wire mesh, kerosene stove, moon. Natural luminous object among the following is Shadows do not give us any information about the shapes of objects. What is light? Its all about contrast. In fact most shadows are not totally black because light usually bounces around the obstruction off other objects. Question 2. An object which does not have a tendency to produce light known as a non-luminous object. Shadows are formed by light, because if light shines onto an object, and the object blocks the light, the light will go sideways of the object, and therefore, a shadow is formed. Most shadows are made up of the umbra and the penumbra. All light is blocked by an opaque object in the umbra. Pinhole cameras consist of a closed box having a small pinhole in the front and having translucent screen at the back. 13.4): a source of light; an opaque object; a screen or irface behind the object. (a) shape of the light source A pinhole camera is a simple camera that consists of a light-proof box, a thin film for a screen and a small aperture or hole to allow the passage of light rays. Question 18. Answer: A smooth shining surface, which rebounds the light back in same or in different direction is called a mirror. This dark Images are formed by intersection of reflected rays whereas a shadows are formed when light does not reach behind the object. Lung cancer may appear as a shadow, with or without a well-defined nodule or mass. A shadow basically is a sort of image produced when light is blocked. . The dark patch formed due to obstruction of light rays by an opaque object is called a shadow. __________ helps us to see objects. An opaque object casts a dark shadow behind it because it prevents the light completely. It consists of a box made of metal or a cardboard that has a fine hole in one face. [6] What is a shadow? WebA shadow is actually just a space or region, where there is no light since an opaque object is blocking light rays. Answer: No, to see the reflection, source of light is required. Then an image is observed similar to the one given : We observe that the light gets reflected from this mirror and it travels in straight lines. On what factor does the proportion of light that enters an object depend? Do you notice any difference? Question 3.
