As mentioned earlier, the chapter related to light, reflection, and refraction of light rays, mirrors, lenses, prisms, etc. In Class 10, you will have to focus on the theoretical part, as well as, the use of these theories to answer questions. After you have completed answering the basic questions in the exercise, you might need a question bank to learn more about this chapter.

### NCERT Solutions for Class 8 Science Chapter 16: Light

The understanding of behaviour of matter and energy at the molecular, nuclear, atomic and even microscopic levels is referred as Quantum physics. Quantum entanglement is one of the central principle of quantum physics, which means multiple particles are linked together in a way that the measurement of one particle quantum state determines the possible quantum of the other particles. Shearing stress is the ratio of the tangential force F to the area of the face BCGH over which it is applied. The ratio shearing stress is divided by shearing strain is the shear module or co-efficient of rigidity, n. In the space, light travels at a speed of , miles per second and sunlight takes about 8 min and 19 sec to reach the surface of the earth.

A concave lens has focal length of 20 cm. At what distance from the lens a 5 cm tall object be placed so that it forms an image at 15 cm from the lens? Also calculate the size of the image formed. An object 50 cm tall is placed on the principal axis of a convex lens. Its 20 cm tall image is formed on the screen placed at a distance of 10 cm from the lens. Calculate the focal length of the lens. Draw the ray diagram in each case to show the position and nature of the image formed when the object is placed: i at the centre of curvature of a concave mirror ii between the pole P and focus F of a concave mirror iii in front of a convex mirror iv at 2F of a convex lens v in front of a concave lens Answer. ## heredity and evolution class 10 questions and answers pdf
