4 REVISE CHAPTER 1 FOR PERIODIC ASSESSMENT Physics Questions on Reflection of light(to be done in class register) Q1. Write the differences between a real image and a virtual image. Q2. Write laws of reflection. Explain the same with the help of a ray diagram. Q3. Draw ray diagrams showing the image formation by a concave mirror when an object is placed (a) between pole and focus (b) between focus and centre of curvature (c) a little beyond centre of curvature Q4. A concave mirror produces three times enlarged image of an object placed at 10 cm in front of it. Calculate the radius of curvature of the mirror. (Solve this question for both the cases, (i) for a real and inverted image, (ii) for a virtual and erect image) Q5. The radius of curvature of a convex mirror used on a moving automobile is 2 m. A truck is coming behind it at a distance of 3.5 m. Calculate the position and the size of the image relative to the size of the truck. What will be the nature of the image? Q6. Define linear magnification produced by a spherical mirror. What is its unit? Q7. An object 4 cm tall is placed on the principal axis of a concave mirror of focal length 20 cm at a distance of 30 cm from it. Find the position, nature and size of the image. Questions on Refraction of light Q1. Refractive index of diamond with respect to glass is 1.6 and absolute refractive index of glass is 1.5. Find out the absolute refractive index of diamond.

5 Q2. Find the refractive index of a material if angle of incidence of ray of light is 45 o and angle of refraction in the material is 30 o. (Given: sin 45 o =, sin 30o = ) Q3. What happens to the speed of light, when light goes from optically denser medium to optically rarer medium? REVISE FOR PERIODIC ASSESSMENT Subject: English 1.
