Class 7 Science Worksheet With Detail Solutions For Chapter 16 Light Pw A real image is formed when light rays coming from an object actually meet at a point after reflection from a mirror or refraction through a lens . in this processes the image formed on the screen is real image. Differentiate between a real image and a virtual image. q2. explain newton disc. ans: the newton disc was invented by isaac newton. it is a spherical disc containing 7 segments. each segment corresponds to one colour in the rainbow. thus, the seven colours present in the newton disc are violet, indigo, blue, green, yellow, orange and red.
Class 7 Science Worksheet With Detail Solutions For Chapter 16 Light Pw How will you identify each one of them? ans. we can identify the mirrors by forming image of an object. plane mirror in case of plane mirror, image will be virtual, erect and of same size as that of object. concave mirror in case of concave mirror, image may be real, virtual and magnified or diminished. (a) an image that cannot be obtained on a screen is called virtual image. (b) image formed by a convex mirror is always virtual and smaller in size. (c) an image formed by a plane mirror is always of the same size as that of the object. (d) an image which can be obtained on a screen is called a real image. When some object is placed very close to the concave mirror we don’t get any image on the white screen placed behind the mirror. such image is called virtual image. The images that are obtained on a screen are called ‘real image’ and that which cannot be obtained on a screen ‘virtual image’. also notice that the image on pinhole camera was upside down.

Ncert solutions for class 7 science chapter 11 light provided by cbse path help students to clear their doubts and to obtain good marks in the exams. all the solutions provided in this article are strictly based on the cbse syllabus and curriculum. Yes, there is a difference in image formation by a pinhole camera and a plane mirror. let us see the differences in the tabular column given below. the images that can be captured on screen are called real images. the images that cannot be captured on screen are called virtual images. real images are always inverted. Answer: when an image cannot be obtained on a screen, it is called a virtual image. the image formed by a plane mirror is virtual, because the image cannot be obtained on a screen when placed either in front of the mirror or behind it. A real image is formed when light rays converge at a specific point. these images can be projected onto a screen, like the image formed by a concave mirror or a converging lens.
